The n°1 protection for hair bleaching, colouring and perming.
Keratin is the most important material, from which hair is made. Allerga is a pure keratin concentrate.
Addition of Allerga to a colour, bleach or perm product not only reinforces the hair, but also protects the scalp against irritations or itching during the processing time.
Application:
– Colouring and bleaching: prepare the mixture as usual and add Allerga.
– Perming: add one half of Allerga to the perm lotion and the other half to the neutralising liquid.
Allerga does not modify the properties of your product through its addition.
