To dye for! - A natural colouration booster

Rahn presents the hair dye performance benefits of Radicare-Eco, an antioxidant based on rosmarinic acid from lemon balm, barley grass and α-glucosyl hesperidin

Changing hair colour has been frequently practiced by both women and men since ancient times. Today, we can differentiate between products on the basis of colour durability after application in terms of semi-/ demi-permanent and permanent dyes.1

Semi-permanent hair dyes provide temporary colouration, and do not require the use of peroxide or a developer. The pigments sit on the surface of the cuticula, and these products are not strong enough to lighten hair colour. The colouration is short-lived and will last up between five and 12 washes.

Demi-permanent dyes do not contain any ammonia but do have enough peroxide to enter into hair cuticles where the pigments are deposited in the first cortex layers. Colouration lasts between 12 to 24 washes, and the products are not as harsh to hair as permanent colourations. Permanent hair dyes are the most efficient; the colouring results from a mixture of substances and involves complex reactions between precursors in the presence of an oxidising agent. The pigments are trapped inside the cortex.2
