Backed by real clinical trials — and it shows

As a nurse, I researched supplements extensively before trying anything. Viviscal has more published clinical trials than any other hair supplement I found. After 6 months, my hair is noticeably thicker — my hairdresser commented on it without me mentioning anything. The marine collagen complex is unique and the two pills daily are easy. Worth every penny for something evidence-based.

New baby hairs appeared after month 3

Consistent use for 3 months and the shedding stopped. I can actually see tiny new hairs growing in at my temples. My bald spots are filling in slowly but surely. The pills are easy to swallow and don't upset my stomach. Only drawback is the price — I wish they had a bigger bottle option with a discount.

A year in and results are minimal

Took Viviscal religiously for 12 months. My hair maybe feels slightly thicker, but nothing dramatic enough for the price tag. My friend swears by it and had great results, so it probably depends on the cause of your thinning. If your hair loss is hormonal or genetic, this alone might not be enough. Wasn't bad — just wasn't the miracle I hoped for.
