Cosphera is one of the best-known hair vitamin brands. What’s in the capsules, who they really help and why a blood test is often the better first investment.
Cosphera describes its capsules as a complex for skin, hair and nails with more than 20 micronutrients. For your hair, biotin, zinc and selenium are the most interesting: all three contribute to the maintenance of normal hair. Then there’s millet extract, a popular ingredient in hair supplements.
The crucial caveat: these nutrients help your hair if you’re lacking them. If your stores are well stocked, an extra capsule adds little. A genuine biotin deficiency is also rare – more on this in biotin for hair loss.
If there’s no deficiency
Rather than going via your stomach, this serum works directly on the scalp: apply it in the evening and leave it on overnight. It combines AnaGain™ and Procapil™, without minoxidil or hormones, for women and men. No. 1 in our comparison.

For a proven deficiency
Biotin, zinc, selenium and millet in one vegan capsule. A sensible supplement if a blood test shows a deficiency.

Capsules with a study
Millet extract, pantothenic acid and L-cystine; three capsules a day for twelve weeks. The manufacturer cites a placebo-controlled study. Intended for women.

Keep in mind
Hair grows about one centimetre a month. If a deficiency was the cause, you’ll see a change after a few months at the earliest.
According to the brand, yes.
Yes, if there’s a deficiency. With a receding hairline and a thinning crown, the cause is usually hereditary – in that case, products for the scalp make more sense. Our guide to hair loss remedies gives an overview.
Vitamins correct a deficiency; a serum works directly on the scalp. The two aren’t mutually exclusive. For gradually thinning hair without a deficiency, we recommend the serum.
