A CREAM which slows the growth of hair by 70 per cent could result in men shaving just once every three weeks. Adonia hair serum uses organic plant oils to weaken hair formation and is being hailed as a healthy element. More than 10,000 people have already put their names on a waiting list for the product. During trials in the U.S. the hair reducer showed an impressive 46 per cent reduction in hair growth after 21 days with a 70 per cent reduction after six weeks. That means the frequency of shaving could be cut by as much as 80 per cent, the equivalent of shaving as little as once every three weeks. Applying the cream sends hair follicles into a catagen or 'resting state. When follicles are in this resting state they are disabled, slowing the growth of existing hair and preventing growth. The longer the follicle is kept in a resting stage, the less hair will grow, so the more the serum is used the weaker and less dense hair becomes. Its makers say users who apply the serum every day will begin to see results within 21 days, with more impressive results emerging after six weeks. DM
