The promise: A beauty-boosting dose of green tea extract, niacin and biotin to support healthy hair growth. They claim to reduce breakage, combat hair loss and generally restore lost lustre. The visible results after 90 days include longer, stronger and thicker hair.

The reviews: These supplements by Ouai, celebrity hairstylist Jen Atkin’s brand, come as highly recommended as the styling products. Comments from “my hair has grown the most it has in my entire life,” to “my hair has never felt or looked SO good!” and “not only did I feel like my hair was getting thicker I could see the one 1/2 to two inches of growth” are just some of the rave reviews from regular users.

Vegetarian? Yes, but not vegan.

Verdict: We approve of the cocktail of ingredients and of the price point. Atkin always personally responds to questions and comments on social media, making her brand feel very authentic and the messaging trustworthy.

The reviews: Given that LYMA is new on the market – and supplements can take up to six months to reveal maximum benefits – there aren’t many user reviews out there. However, it’s gaining approval from the pros, such as nutritional scientist Simon White who says its ahead of its time: “It uses patented ingredients that are clinically formulated to work like no other supplement on the market. LYMA is the definition of a true super supplement.” It’s also been coined the ‘supermodel supplement’, thanks to LYMA’s co-founder, A-list fitness coach Russell Bateman, and his clientele of early adopters. The likes of VS Angel Roosmarijn de Kok can’t get enough.
