What Is The Best Product to Use After Hair Transplant?

Supplements: what works and what does not

The evidence for supplements in post-transplant healing is mixed but the downside is low. Our protocol recommends: a standard multivitamin with B-complex (for general hair metabolism), biotin 2,500–5,000 mcg daily (for keratin production), zinc 15–25 mg daily (for follicle health and wound healing), and vitamin D 1,000–2,000 IU daily (deficient in most European patients year-round). Start these a week before surgery and continue for 6 months.

What does not work: saw palmetto and other "natural DHT blockers" (mildly effective for hair loss in general but do nothing for transplant survival), collagen peptides (no evidence for hair specifically, marketing claims only), and "hair growth gummies" (basically multivitamins at 5x the price).

Month 2 onwards: PRP and minoxidil

At month 2, some protocols introduce PRP (platelet-rich plasma) and/or topical minoxidil to boost the growth phase of the transplanted follicles and protect surrounding native hairs from shock loss.

PRP uses your own blood platelets to stimulate follicle activity. Most Istanbul clinics include 1–2 PRP sessions in the post-op package. Additional PRP sessions (every 3–4 months for the first year) are optional and may accelerate regrowth by 10–20% based on available studies. Cost: €150–300 per session.

Minoxidil 5% applied topically once or twice daily is approved for male and female hair loss and can be used starting week 4 if cleared by your surgeon. It accelerates hair cycling and is particularly useful for patients with significant native hair thinning around the transplanted area. Some patients experience shedding in the first 2–4 weeks of minoxidil use (a normal side effect that represents weak hairs being replaced by stronger ones). Cost: €15–30 per month.

What to avoid in the first 3 months

Avoid: hair dyes and bleaches (not before month 6), strong medicated shampoos like anti-dandruff zinc pyrithione products (not before month 3), hair styling products with alcohol (gel, spray, wax) until week 6, hot showers on the scalp (warm only for the first month), chlorine pools until month 2, salt water until month 3, tight hats and helmets until week 4, and vigorous scalp massage until month 2.

And the most important "do not": do not buy whatever product a YouTube influencer is promoting. Stick to your clinic's protocol for the first 3 months. After that, you can experiment.

Frequently Asked Questions

Is there a single "best" shampoo after a hair transplant?

For the first 10 days, use only the post-op shampoo your clinic provided. After day 14, any gentle sulfate-free shampoo with a balanced pH works. There is no magic ingredient — the key is "gentle" and "consistent".

Do I need special supplements after a hair transplant?

Basic support (multivitamin, biotin, zinc, vitamin D) is reasonable and low-risk. Fancy "hair growth" supplements are mostly marketing. Eat enough protein (1.5 g per kg of body weight per day) — that matters more than any supplement.

Should I use minoxidil after my transplant?

Discuss with your surgeon at the week 4 follow-up. It is not mandatory but is helpful for patients with surrounding native hair thinning, and it can slightly accelerate the growth phase. Start only after the grafts are fully anchored.

How long should I use the saline spray?

10–14 days of frequent use (every 3–4 hours). After scab fall-off, saline spray is optional and used only if itching persists.

Can I use my normal shampoo after a month?

Yes, most normal shampoos are fine from week 4 if they are sulfate-free and pH-balanced. Avoid anti-dandruff shampoos with strong active ingredients for the first 3 months.
