4 Months After a Hair Transplant: What Is Normal at Months 4 and 5

Seeing very little at four months is too early to judge. One HairLossTalk poster, four and a half months after a 2,500-graft transplant, wrote in May 2008: "So far, I am really disappointed." On 2 June, after a trim, the same poster wrote: "I can see a lot more thin hairs growing in than I thought."

This part of our hair transplant guide covers months 4 and 5, front and crown. The poster's HairLossTalk thread runs from 14 May to 6 June 2008.

The American Academy of Dermatology (AAD) says: "Most patients see results between six and nine months after surgery. For some patients, it takes 12 months."

So month 4 comes before that window. The AAD doesn't describe month 4 or month 5 on its own.

What Grows by Month 4: What the AAD and Clinics Say

The AAD's last marker before month 6 is month 3: "By the third month, the hair may look thinner than before you had the transplant." It gives no percentages and no crown timing.

Three Bangkok clinics publish when new growth starts. HairTran says: "New growth begins at around 3-4 months, with visible improvement by 6 months and full results within 12 months."

The same HairTran page lists a follow-up step that reads "6 Months - Noticeable growth begins." So one line puts new growth at three to four months, and the other puts noticeable growth at six.

Bangkok Hair Clinic says: "New growth usually begins between weeks 10-16, with full results visible within 12 months." Sixteen weeks is just under four months, so a patient at month 4 sits at the end of that window.

CosmoPrime says: "Initial growth appears at 3-4 months; full results by 9-12 months."

Clinics outside Thailand say much the same. Treatment Rooms London says "It can take between three and six months for your new hair to emerge," and adds: "If you haven't seen any new hair growth by the four-month stage, don't panic."

Dr Sam Sukkar describes months 4 to 6 as the stretch when "the mirror usually starts getting friendly again."

Front Versus Crown at Month 4

Nashville Hair Doctor says "the frontal areas like hairlines typically also grow faster than the crown." Eugenix Hair Sciences says growth "generally begins around month four across the scalp" and that "Minimal crown growth at month four is expected."

So a hairline with some new hair next to a crown that looks unchanged fits what these clinics describe at month 4. The crown section below covers why.

Month 5: What Changes

No medical society page or paper we read describes month 5 on its own. The AAD's next marker after month 3 is six to nine months.

On the crown, Eugenix says: "At month four or five, patients frequently report that the crown appears to be doing nothing at all."

HairTran puts "visible improvement by 6 months." Trichogenics lists "No new growth by month six." among its warning signs, so by that clinic's own list, month 5 is still before the point it treats as a concern.

Posters at month 5 report both slow and clear progress. In 2018, one poster at five and a half months asked whether they could "expect much more density in my crown area." In January 2026, another at five months wrote: "Hair's grown a lot compared to before, which is nice."

Both threads are in the patient table further down. Our 6 months after guide picks up at month 6.

What Percentage of Growth Should You Have at 5 Months?

No study or medical society we found publishes a month-by-month growth percentage for hair transplants. The AAD gives none, and the ISHRS patient page gives no timing at all.

Clinic blogs do publish percentages for months 4 and 5. They differ from each other, and we found no study behind them, so we don't repeat them.

A more useful question for your clinic: what did your surgeon expect by now for your graft count and the areas treated? That's our suggestion, and the surgeon who planned your grafts is the one person who can answer it for your case.

Why Is My Crown Slower Than My Hairline?

In 2007, a patient in the UK about five months past a second procedure asked Bernstein Medical, a US clinic: "New hair in the front part of the head is growing well, but the crown is growing slow. Is this common?"

The answer: "Yes, it is typical for hair in the crown to grow more slowly than the front and top of the scalp." It gave no reason.

Eugenix gives one: "Blood supply to the crown is lower than to the frontal and mid-scalp zones." It adds: "This is the main reason the crown grows on a slower schedule than the front."

Its page cites no study for that point, and we found no paper or medical society that tests the explanation.

Dr Sukkar says: "Hairline work often appears sooner than crown work." The same page says "The crown areas can take longer than 12 months".

Perseus Style says the crown "lags by four to six weeks" behind the hairline.

The blood-supply idea also runs through patient forums. One HairLossTalk reply from 26 March 2019 says: "Don't forget the crown is always slow due to the limited blood supply compared to the rest of the head."

So a thin crown at month 4 or 5, next to a hairline that is starting to fill in, matches what each of these sources describes. Ask your surgeon when they plan to judge the crown in your case.

Thin, Wiry or Curly Early Hairs

The first hairs at months 4 and 5 often look nothing like the hair you're aiming for. KSL Clinic says the new hair "may appear fine or a little thinner than your other follicles," and that "although it may be thin and wispy, it will thicken over time."

Nashville Hair Doctor says: "At first, the new hair coming in may be thin and curly." It says the hair "will thicken and straighten out as it grows longer."

At Wimpole Clinic, surgeon Dr Ahmad Moussa describes early growth this way: "it might look a little bit sparse, might look a little bit spiky and wiry."

Treatment Rooms London says "these new hairs are thin and almost transparent in their appearance." Perseus Style compares them to body hair: "At first, the new hair may be fine and curly, like body hair".

We found no medical society page or paper on how early transplanted hair looks.

Forum posters describe feeling the hairs before they can see them. A 2006 HairLossTalk poster at 19 weeks wrote: "i can feel lots of little hairs with my fingers."

A reply in the same thread said: "They come out so thin and light that they are not really visible with the naked eye." For the first sprouting at month 3, see our 3 months after guide.

Patchy or Uneven Growth at Months 4 and 5

Several clinics say growth at this stage comes in unevenly. Nashville Hair Doctor: "Do not get discouraged by the fact that the transplant area may look patchy at this stage." Treatment Rooms London: "The growth will initially be patchy and thin."

Trichogenics says: "The new strands may appear thin and patchy, which is completely normal at this point." Dr Sukkar says: "If a section looks thinner, it may simply be behind in the growth cycle."

A 2026 review of FUE complications by Romera de Blas and colleagues in Frontiers in Medicine gives the timing for poor growth as "6-12 months post-op." So months 4 and 5 come before that window.

Existing hair makes the picture harder to read. A 2008 HairLossTalk reply said: "Its always harder to see new growth amongst existing hair."

Light and wet hair change it too. A 2018 poster at five and a half months wrote: "From a few feet away it looks fine with dry hair but close up with slightly damp hair and some light not so much."

Shedding at Months 4 and 5

Two types of shedding get mixed up at this stage. The transplanted hairs shed early: the AAD says "between two and eight weeks after the surgery, the transplanted hair will fall out. This is normal."

The second type is shock loss, where your own existing hair sheds.

The Frontiers in Medicine review says this shedding of native hair around the transplant "typically occurs within 2-8 weeks after surgery, with regrowth usually beginning around 3 months postoperatively." It adds: "Reported incidence varies widely, ranging from 0.15 to 15%."

The donor area at the back can shed too. The same review says donor shedding "typically develops 2-4 weeks after surgery and resolves spontaneously within 3-6 months," and shows up as "a more localized thinning patch."

Months 4 and 5 fall inside that three to six month window. So a thin patch at the back now may still be inside the period the review describes.

The review also says shock loss isn't always temporary: "Although typically temporary, a permanent reduction in native hair density may occur, particularly in follicles nearing the end of their growth cycle or already miniaturized."

If you see hair falling out now, show your surgeon photos so they can tell you which type it is.

Pimples, Ingrown Hairs and Bumps

Bernstein Medical says: "It is common to get small pimples that begin to erupt 2-3 months post-op." It adds: "If they persist, you should see your doctor."

Charles Medical Group says "Bumps typically appear between 2 days and 6 months post-procedure." It says bumps that show up from 4 to 12 weeks, or several months, after surgery are often related to ingrown hairs during the regrowth phase.

The Frontiers in Medicine review covers folliculitis, which means inflamed hair follicles. Zhou and colleagues "reported an incidence of 12.1%" across donor and recipient areas, and the review says "The onset typically occurs within the first 1-4 weeks after surgery." So bumps at month 4 or 5 start later than that.

The review also lists cysts, with timing "Weeks to months post-op". It describes them as "Small, firm nodules at punch sites or in the recipient area; may become inflamed or infected."

A bump that hurts, spreads or keeps coming back goes to your surgeon or a local doctor.

Charles Medical Group says "Any firm, persistent nodule that does not resolve within a few weeks should be evaluated by the surgeon." We give no home treatment advice, so follow your own surgeon's instructions.

When to Contact Your Clinic

The Frontiers in Medicine review lists the signs of infection as "pustules or honey-colored crusts, increasing pain, swelling, erythema, purulent drainage, and tenderness or enlargement of regional lymph nodes." Erythema means redness.

Charles Medical Group says: "Patients should contact their surgeon immediately if they experience any of the following:" Its list includes:

• fever
• pus, discharge or a bad smell
• redness that spreads
• severe pain
• scalp skin turning dusky or black

Dr Sukkar says: "If anything feels off, excessive bleeding, unusual pain, signs of infection, or poor healing, contact the office promptly." KSL Clinic says patients "can and should consult their surgical team if they have concerns."

For growth worries, the pages we read draw the line in different places. Trichogenics lists "No new growth by month six." Perseus Style lists "No visible growth whatsoever in any part of the recipient zone by week 18", which is about month 4.

We set no threshold of our own for too little growth. Ask your clinic what it expected by now for your case, with dated photos in hand.

Following Up With a Thai Clinic From Home

If you flew to Thailand for your transplant, months 4 and 5 happen after you're home. None of the Thai clinic pages we read describes a scheduled check at month 4 or month 5.

We compare what clinics publish and haven't visited them.

For people abroad, HairTran says: "Through our dedicated online follow-up system for international patients, you can send photos of your transplanted area for our doctors to review and track your progress." It says it can also "arrange a video call with your doctor".

So at month 4 or 5, HairTran's route is its photo system. HairTran also says its one-year guarantee applies if "you have attended all scheduled follow-up visits."

Hairsmith says: "After one year, if there are areas where the hair hasn't grown well or hasn't grown at all, we will do a free touch-up without any extra charges." (read 26 October 2026). That's one clinic's policy, and it applies after a year, not at month 4.

If you're still choosing a clinic, ask how follow-up works once you're home. Ask who reviews your photos, how fast they reply, and whether a missed visit affects any guarantee.

Tracking Progress With Photos

HairTran's 12-month assessment ends with the doctor "comparing before-and-after photos". Its online follow-up for international patients also runs on photos.

Our own suggestion: photograph the hairline, top and crown once a month, in the same spot and light, at the same distance, with dry hair styled the same way. Keep that setup for the duration of the first year, so each month compares with the last.

The 2018 poster's note about damp hair and light shows how much those conditions change what you see.

Care at Months 4 and 5

Follow your own surgeon's instructions, and take any medication question to your own doctor.

Our hair transplant guide has separate pages on aftercare, medication and PRP.

What Patients Posted at 4 and 5 Months

These are forum posts from patients at months 4 to 5.5, oldest first. Each is one person's account, and none is typical of anything.

The replies in these threads come from other forum users, not doctors. Most urge patience.

A 2009 reply: "4 months is too soon to be evaluating anything." A 2017 reply: "4 months is super early man, give it at least a full year before you lose your mind."

Not all do. In the 2019 thread, one reply said "at 4 months I would expect a better result."

Another reply in the same thread said: "4 months is way too early. Give it 4 more months at least."

The crown comes up again and again. The 2006 poster wrote of it: "Its much more difficult to tell whats happening there."

The 2008 poster wrote: "I wasn't expecting great coverage in the crown, but I was expecting better than 'no coverage.'" The 2019 poster, on 30 April: "Crown still has some way to go but still only 6 months in".

The 2008 poster also wrote: "I have always read that the 5-6 month mark is supposed to be a big turning point." The 2026 poster at five months asked: "it should keep getting better around 8 months+, right?"

Our reading of these seven posts, which isn't a statistic: three posters reported visible change within weeks of writing, and one at month 5 described real growth. Not all of them did.

What Comes Next

The AAD's marker is the next one to watch: "Most patients see results between six and nine months after surgery. For some patients, it takes 12 months."

Hairsmith, a Bangkok clinic, advises waiting 12 to 18 months to see the final outcome before considering more surgery (read 26 October 2026). HairTran and Bangkok Hair Clinic say full results come within 12 months, and CosmoPrime says "by 9-12 months". Dr Sukkar says "The crown areas can take longer than 12 months".

Our guide also covers the ugly duckling phase. For the whole first year of hair transplant recovery in order, see our recovery timeline.

Frequently Asked Questions

Why do I see no results 4 months after my hair transplant?

Month 4 is early. The AAD says "Most patients see results between six and nine months after surgery," and some take 12.

Bangkok Hair Clinic puts the start of new growth at weeks 10 to 16, and the 2026 Frontiers in Medicine review gives the timing for poor growth as "6-12 months post-op." If you're worried, send your clinic photos and ask what it expected for your case.

What should I expect 5 months after a hair transplant?

Thin, uneven new hair is what clinics describe, often with the crown behind the hairline. No medical society describes month 5 on its own, and the AAD's next marker is six to nine months. HairTran puts "visible improvement by 6 months," and Trichogenics lists no new growth "by month six" as a warning sign.

Is it normal for the crown to show less than the hairline at 4 months?

Clinics say yes, usually. Bernstein Medical told a patient in 2007: "Yes, it is typical for hair in the crown to grow more slowly than the front and top of the scalp."

Eugenix says "Minimal crown growth at month four is expected" and points to lower blood supply. We found no study that tests that explanation.

Can transplanted hair fall out after 5 months?

The AAD places shedding of transplanted hair at two to eight weeks after surgery. Two pages we read put the end of that shedding later: Wimpole Clinic says about 3.5 to 4.5 months after surgery, and Perseus Style says most transplanted follicles have finished by days 90 to 150. The shedding the 2026 review describes is shock loss of your own existing hair and shedding in the donor area, not the grafts. If you see hair falling out now, show your surgeon photos.

What percentage of growth should I have at 5 months?

No study or medical society we found publishes one. Clinic blogs give percentages for this stage that differ from each other, and we found no study behind them. Ask your surgeon what they expected by month 5 for your graft count and the areas treated.

When does a hair transplant start to look good?

The AAD says most patients see results between six and nine months after surgery, and some take 12. HairTran puts "visible improvement by 6 months." Hairsmith, a Bangkok clinic, advises waiting 12 to 18 months to see the final outcome before considering more surgery (read 26 October 2026).

How We Researched This Page

We read the AAD's hair transplant page, the 2026 Frontiers in Medicine review, the ISHRS patient page, pages from five Thai clinics and 11 pages from 10 sites outside Thailand. We also read 13 patient threads, 12 on HairLossTalk and one on the Tressless community, posted from 2006 to 2026.

The Reddit and RealSelf threads we found wouldn't open for us, so we quote none of them. We publish no growth percentage for any month, because no study or medical society we found publishes one.
