Hair feels a thicker.

My nails have always been the weak point — paper-thin, peel constantly. Took these religiously for about three months. They're harder now. Hair feels a bit thicker too but that might just be wishful thinking on my part.

Olivia H. Brighton · 19 February 2026

Great value.

Bought for my wife but I've been taking them too since she rates them. 180 tablets per pot is great value, lasts ages. The zinc and selenium combo with biotin is a sensible formula.

Naveed I. Coventry · 6 April 2026

Highly recommended.

Started these after my hair stylist mentioned biotin. Notice my hair shedding less when I brush. Three tablets a day is a bit of a faff but I take them with breakfast and it's fine. Will keep going.

Cherelle J. Hackney · 2 March 2026

Reasonable product, fair price.

Reasonable product, fair price. Selenium content is a nice bonus, that's not always included in beauty supplements. Took off a star because I find the tablets quite plain looking but that's hardly a real complaint.

Anna K. Cambridge · 21 January 2026

Doing what they say on the tin.

Six month supply for the price is honestly hard to beat. Vegan tablets which matters to me. My nails are noticeably stronger and my skin feels better hydrated. Doing what they say on the tin.
