Hair transplant 6 months after: density still building, finer hairs and the signs that justify a check-up
Six months after a hair transplant, regrowth is well under way but not finished. The new hairs, which usually appear around the fourth month, have started to lengthen, yet they are still short, often finer and lighter than the hair around them, and the grafted area can still look uneven, especially on the crown. This in-between picture matches the usual timeline, since the NHS expects the full result between 10 and 18 months after surgery (NHS, 2023).
These milestones also help anyone preparing a hair transplant in Turkey who wants to picture the middle of their first year. It is often the point at which friends and family start to notice a change, even though the result cannot yet be judged.
Three situations, however, are worth raising without waiting until the twelfth month: an area with no regrowth at all while neighbouring areas are filling in, density that falls back from one month to the next, and painful spots that keep returning or redness that spreads with burning or itching.
What does the grafted area look like at six months?
Hairs that are still short, fine and sometimes lighter
Hairs that emerged between the third and fifth months have only a few weeks or months of growth behind them. They already blend with the surrounding hair, but they are not long enough to hide the scalp under direct light or straight after a shower. Their shafts can look finer than those of the hair at the back of your head that they came from, and their shade a little lighter.
The difference shows mostly at close range, when you part the hair or photograph your scalp with a flash. From a normal distance, the grafted area already looks quite different from the early months, even though its density is still building.
Coverage that is still patchy
Transplanted follicles do not all restart growing on the same date. At six months, some have been producing a hair for several weeks while others have only just left their resting phase, which leaves a patchwork of areas that are already full and areas that are still sparse. Seen up close, with a magnifier or a dermatoscope, an area that looks empty in a wide photo sometimes shows the tips of hairs that have only just broken through.
Why does density still look incomplete?
At six months, much of what is missing from the density comes down to how the hairs that have already emerged look, since they have reached neither their final length nor their final calibre. To estimate how much a donor area can cover, some surgeons use an index called the coverage value, which multiplies the number of follicular units per square centimetre by the number of hairs in each unit and by the diameter of the shafts (Romera de Blas et al., 2026). Applied to the grafted area, the same calculation explains why an unchanged number of hairs covers more as the shafts thicken, and lengthening adds to the effect, because longer hairs overlap and hide the skin better.
The result percentages often quoted for six months, which range from half to two thirds of the final result depending on the clinic, do not rest on any published measurement that holds for every patient. Your density at this stage depends on the area treated, the number of grafts, how they were distributed and the hair you started with. It is best read by comparing it with your own photos from previous months.
A crown that lags behind the hairline
At six months, the crown, the top of the head where hair is arranged around a whorl, can look less advanced than the front of the scalp. How grafts are shared between the two areas is decided before surgery, according to the donor reserve and the priorities of the plan, and our complete hair transplant guide explains these trade-offs.
A gap between the two areas at this stage does not mean the crown grafts have failed to take. The crown’s appearance is better judged towards the end of the full-result window given by the NHS, and the full hair transplant timeline places this catch-up within the first eighteen months as a whole.
Wavy hair, redness, spots: what you may still notice
Hairs that grow wavy or curly
Some transplanted hairs can grow wavier or curlier than the original hair. In a series of 980 women followed after hairline correction surgery, this affected 38 patients (3.9%): in 36 of them the transplanted hairs began growing curly around the fourth month, and in the other two between the sixth and eighth months, when their growth direction was obstructed or compressed by the existing hair (Park et al., 2024). The authors note that the cause and prevention of this effect remain poorly understood. If you notice this change, photograph the area and let the team following you know, so that it can compare how it evolves over the following months.
Redness around the hairs, or spots that keep coming back
Folliculitis, an inflamed follicle that looks like a small red or pus-filled spot, usually starts between the first and fourth week after surgery (Romera de Blas et al., 2026). Painful spots that come back at six months therefore fall outside that window and call for medical advice, all the more so as the same review links extensive or recurrent forms to delayed regrowth and the loss of some grafts. Mild, stable redness around hairs that are growing well is a different matter: according to the authors, it can persist for several months after surgery and carries no diagnostic weight on its own.
More rarely, new redness spreads around the grafts after an initial period of satisfactory regrowth, together with itching, pain or burning, while some hair openings disappear. This picture should prompt a search for lichen planopilaris, a chronic inflammation of the follicle, by means of a dermatological examination that may go as far as a biopsy (Romera de Blas et al., 2026).
Hair falling out at six months: grafts or native hair?
Finding hairs on your pillow or in the sink at six months does not, on its own, call the transplant into question. The NHS points out that we can lose 50 to 100 hairs a day, often without noticing (NHS, 2024). Shedding on that scale, spread across the whole scalp, is part of the normal renewal of hair.
Heavier, diffuse shedding that appears within a few weeks can have a temporary cause unrelated to the transplant. According to the NHS, temporary hair loss can follow an illness, a period of stress, weight loss or iron deficiency (NHS, 2024), and this situation deserves medical advice to identify the cause before any supplement is taken.
A transplant moves hair taken from the back of the head, but it does not stop the androgenetic alopecia that continues to affect your native hair. The NHS warns that the hair around a transplant may keep thinning (NHS, 2023), so a native area that looks sparser than before surgery may reflect native hairs miniaturising, with no link to how the grafts took. Romera de Blas et al. (2026) also point out that poor adherence to medical treatment can lead to native hair loss out of proportion to the transplanted hair, which unbalances the result. If you have not yet discussed it, show your doctor how this native hair is changing: it is for them to judge whether a treatment for hereditary hair loss makes sense, or whether to continue the one you are taking.
Native hairs lost to shock loss, the reactive shedding of the weeks after surgery, usually start growing back around the third month. The review by Romera de Blas et al. (2026) notes, however, that a permanent drop in density is possible when the follicles involved were close to the end of their cycle or already miniaturised. At six months, a native area that is still sparse has therefore passed the usual regrowth window and is worth showing to the team.
Styling, colouring, sun: getting back to your habits at six months
According to the NHS, grafts need very careful handling for 2 weeks after the operation, as they are not yet secure, and you may be told to exercise less in the first month to limit scarring (NHS, 2023). By six months, scissor and clipper cuts are possible over the whole head, grafted area included, and sport, swimming, helmets or caps are no longer subject to recovery instructions. A very short cut will, however, show the scalp between hairs that are still fine, as well as the donor-area scars, and keeping a little length on top lets you make the most of the coverage already achieved.
Colouring or highlights can be done on a healed, non-irritated scalp, provided you tell your hairdresser about the transplant and test the dye first, since the NHS recommends a strand test at least 48 hours before colouring, along with the instructions on the packet (NHS, 2025). If redness persists, or if you are considering bleaching or chemical straightening, which are harsher on the skin, ask the team first.
Under hair that is still sparse, the scalp remains exposed to ultraviolet light. A wide-brimmed hat during long spells in the sun helps protect the grafted area from sunburn.
When should you ask for a check-up at six months?
Poor regrowth is usually identified between 6 and 12 months after surgery (Romera de Blas et al., 2026). Six months therefore opens that window: it is the first point at which an area that has stayed empty can be assessed with enough hindsight, even though the picture keeps becoming clearer over the second half of the year.
| What you see at six months | What to do |
|---|---|
| Short, fine, lighter hairs | Usual follow-up |
| Crown behind the hairline | Judged later, dated photos |
| Clearly curly hairs | Photos and team advice |
| Sudden diffuse shedding | Medical advice to find the cause |
| Area with no regrowth at all | Ask for a check-up |
| Density falling back | Ask for a check-up |
| Painful spots that keep returning | Prompt medical advice |
| Spreading redness, burning | Dermatology assessment |
The check-up starts with photos: the team sets your current pictures against your pre-operative set and those from the months since, particularly the one taken at the three-month mark after the transplant, then looks at the skin and how the hair is distributed on those images. If an in-person scalp examination seems necessary, a dermatologist in your area can carry it out. When one area is simply starting later than the others, our piece on delayed hair growth after a transplant describes the causes to look for and reasonable waiting times.
Even if an area is disappointing at six months, the question of a further session waits until regrowth has finished, usually around twelve months after surgery (Romera de Blas et al., 2026). What can justify one is discussed in detail on our second hair transplant page.
What the second half of the year can still change
Between the sixth and twelfth months, the hairs that have already emerged lengthen and gain body, while those that left their resting phase later gradually fill in the areas that are still light. The texture and shade of the transplanted hairs tend to move closer to those of the donor area they came from, and styling becomes easier as the strands start to overlap. Some areas will keep improving after the first anniversary of the procedure.
A set of photos taken at this stage, with dry hair and the same views and lighting as your earlier sets, will serve as the comparison when the time comes to assess a hair transplant one year after surgery, the point at which most of the result can be read.
Sending your six-month photos to our team
The 12-month post-operative follow-up, carried out remotely, included in our packages covers this whole period. You can send your six-month photos to your dedicated English-speaking patient coordinator, and our team compares them with your earlier sets to tell you whether progress is on track or whether an examination is needed. Questions about a haircut or colouring can go through the same exchange.
If you are still preparing your procedure, our partner clinic in Istanbul, selected for its facilities and its surgeons’ experience, performs the transplant under local anaesthesia. Your 5-star hotel, VIP transfers and the same patient coordinator frame your stay, and the follow-up continues once you are back home. How the stay unfolds and how dates are arranged are set out on the page dedicated to hair transplant in Istanbul, and your quote, free and with no obligation, reaches you within 24 hours.
