A Japanese study in 2001 revealed that men in their 20s are colouring their hair more than before. Men, like women, dye their hair for aesthetic reasons, variety and to cover grey. Luckily, safe and natural hypoallergenic products are available for them, as well.
Effects of Chemical Dyes
Permanent and semi-permanent chemical hair dyes contain harsh chemicals such as ammonia and peroxide. Para-phenylenediamine (PPD), a notorious chemical used in the first hair dyes, is still used today and has been known to cause hair loss and severe scalp irritation.
Meaning of Hypoallergenic
PPD is listed as an allergen to avoid by truetest.com and a carcinogen by preventcancer.com. By definition, hypoallergenic products are less likely to cause an allergic response in users.
Natural Hair Color for Men
Herbal and vegetable dyes and food-based ingredients are the least toxic and can leave hair healthy and shiny, according to the Environmental Working Group. Hair dyes made from natural sources and botanicals that don't contain PPD are hypoallergenic, causing less damage to the hair and scalp.
According to hennahairdye.net, henna, a flowering plant from Egypt, is a natural and safe hair and body dye. The colour is temporary and works by covering the hair rather than penetrating the shaft. It gradually gets darker, so it's not meant for those who wish to lighten their hair.
Where to Buy
Natural, hypoallergenic hair dyes for men are available at most major health and natural food stores and beauty supply stores. The colour treatments are also available at environmentally conscious hair salons.
