Saw Palmetto DHT Shampoo

Saw palmetto fruit extract is the ingredient the name is built on. Its fatty acids and phytosterols have inhibited 5-alpha-reductase, the enzyme that converts testosterone to DHT, in laboratory assays. That is a real finding, and it sits a long way from a demonstrated effect on a human scalp. The clinical work on saw palmetto is limited, mostly oral, mostly small, and none of it tests a rinse-off shampoo. Nobody should read the word DHT on this bottle and understand it as finasteride in another format.

Niacinamide at 1% is the ingredient here with the least argument attached to it. It supports the skin barrier and settles redness and irritation, which is a scalp comfort benefit and not a growth one, and it is the reason this wash suits a scalp that a topical treatment is drying out.

Caffeine at 0.2% is the concentration used in the published leave-on work. That study was open-label, it was funded by the manufacturer of the product being tested, and it set caffeine against minoxidil as a substitute for it. That design does not make caffeine a replacement for minoxidil, and nothing on this page should be read that way. What is better established for a shampoo specifically is delivery: caffeine massaged in for two minutes and rinsed off has been measured reaching the follicle and staying detectable there for around a day. Getting an ingredient to the follicle is a long way from proving it grows hair, and the honest summary is that caffeine in a wash is plausible and thinly evidenced.

Biotin, copper tripeptide-1 and acetyl tetrapeptide-3 make up the rest. Biotin helps hair in people who are genuinely deficient, and two minutes of scalp contact does not change that. The two peptides have small, largely manufacturer-run trials behind them in leave-on serums, and less again in something you rinse away. They are in the formula and they are unlikely to do any harm, and we are not going to build a claim on them.

You are going to wash your hair anyway, so the wash step is a free slot in the routine. This is the one to choose if your scalp runs oily or feels congested, and it pairs with Minoxidil Topical Solution USP, 5%, which is the only product in this range with strong regrowth evidence behind it. The 1% niacinamide is the reason to reach for this over a harsher wash when a topical has left your scalp tight or itchy, and the Caffeine Conditioner is the sensible follow-on for the lengths. If your main complaint is flaking and not oil, the Anti-Dandruff Shampoo is the better fit and you can alternate the two.

Every time you wash your hair, three or four times a week.

1. Wet your hair and scalp thoroughly with comfortably warm water, never hot.
2. Work a coin-sized amount, roughly 5 mL, into a lather and rinse it straight back out. This first wash clears oil and styling product so that the second one reaches skin.
3. Apply a second coin-sized amount, this time aimed at the scalp itself and not the lengths, and massage it in with your fingertips for about a minute.
4. Leave it on for two to three minutes. This is the only point in the routine where the actives get any contact time, and rinsing straight away leaves you with an ordinary shampoo.
5. Rinse thoroughly, then condition the lengths and ends and keep the conditioner off the scalp.

Wash before you apply a topical, never after. If you are using minoxidil, shampoo first, dry the scalp completely, then apply the dose. Washing a few hours after you have applied it throws that dose away.

The effect is cosmetic and it arrives quickly. Within a wash or two the scalp feels cleaner and less oily, and where niacinamide settles itching or tightness it usually does so inside a fortnight. What you should not expect is a change in hair density. If you buy this bottle for that, you will be disappointed at three months and again at six. Regrowth, where it happens, comes from minoxidil, and the job of a shampoo is to keep the scalp in reasonable condition while that runs.

For external use only. Keep it out of the eyes and rinse with plenty of water if it gets in. If your skin irritates easily, patch test on the inside of the forearm and wait a day before using it on the scalp. Stop using it if you develop a rash, persistent itching, or redness that does not settle.

This is a cosmetic shampoo and it is not a medicine. It does not treat hair loss, dandruff or any scalp condition as a disease, and it will not do what a prescribed treatment does. If your scalp is red, inflamed or painful, or if your shedding is sudden and heavy, see a doctor rather than changing shampoo.

Saw palmetto carries interactions worth knowing about when it is swallowed, including with anticoagulants and in hormone-sensitive conditions. Those cautions attach to oral doses and the exposure from a rinse-off wash is very small, though it is still worth mentioning to your doctor if you are on medication. Not for use on children.

Keep out of reach of children. Store at room temperature with the cap closed.
