A large market of aftercare products surrounds hair transplants, and much of it is priced well above anything the evidence supports. The products that matter are usually the ones your clinic gives you or tells you to use. Here is what tends to be necessary, what is a reasonable extra, and what is mostly marketing.
What is usually necessary
To show what a real set of instructions looks like, I have used one US surgeon’s published post-operative instructions (Dr. Ali Totonchi) as an example. Your clinic’s will differ in the details.
- The washing routine your clinic prescribes. Dr. Totonchi’s instructions say not to wash for at least 72 hours, then to pour lukewarm lather gently over the grafts with a cup, without direct shower pressure, and not to touch the grafts with your fingers for 7 days. Use whatever shampoo your clinic provides, in the way it says.
- A spray to keep the grafts moist. The same instructions recommend spraying the grafts with sterile water several times a day in the first 48 hours, then a diluted saline mist up to twice a day for two weeks. Our guide to flying after a transplant explains why this matters on a plane too.
- Any medication you are prescribed. Pain relief and any antibiotics or anti-inflammatories are part of the medical treatment, not optional extras.
Reasonable extras
- Something to protect the grafts while you sleep, such as a clean, soft pillowcase or travel pillow. Dr. Totonchi advises sleeping with your upper body raised for the first nights after frontal work.
- A mild shampoo later on. another clinic guide recommends a gentle, pH-balanced, sulfate-free shampoo. Once you are past the initial phase your clinic prescribes, an ordinary mild shampoo of that kind should do; I found no evidence that expensive “post-transplant” brands work better.
- Sun protection. Dr. Totonchi’s instructions say to avoid too much sun on the grafts for 90 days and, after 14 days, to use spray sunscreen or a loose hat if outdoors for more than 30 minutes.
Usually unnecessary
- Premium “growth” serums. They are heavily marketed in the weeks after surgery, when people are anxious about results. None of the clinic instructions I reviewed required them, and I found no good evidence that they improve graft survival over standard care.
- Transplant-branded supplements. If you take supplements, tell your surgeon, since some can affect bleeding. There is no good evidence that branded “recovery” supplements beat a normal diet.
Restarting minoxidil and finasteride
This is a common question because it affects your medication, not just optional products.
- Minoxidil is applied to the scalp, so it is usually paused while the skin heals. Acibadem International says topical minoxidil is commonly postponed during healing, and Dr. Totonchi’s instructions say to check with your doctor before restarting it after the first month.
- Finasteride is a tablet, and practice varies. Acibadem says its timing follows the prescriber’s advice, which differs between clinics, so ask before stopping or restarting it.
- Medicated shampoos such as ketoconazole: follow the specific dates your clinic gives.
Our medication vs transplant guide explains why many surgeons recommend continuing these treatments long term.
A simple rule
If your clinic gave you a product or told you to buy it, treat it as part of your medical aftercare. If it is marketed to you afterwards, in an email, an advert or a checkout upsell, ask whether it solves a real problem or simply targets how anxious recovery makes people feel.
Frequently asked questions
Will skipping expensive serums hurt my results? Not according to anything I found. Graft survival depends far more on the surgery and on following the core instructions (washing, medication, sleeping position, protecting the grafts) than on premium products. Our recovery timeline explains what happens when.
Should I ask my clinic which products it recommends and which it just sells? Yes. A straight answer is a good sign, like the transparency questions in our guide to clinic guarantees.
Can I use my usual shampoo in the first two weeks? Only if your clinic says so. This is the period when following its specific instructions matters most.
