Comb through dry hair with a normal comb to remove tangles. Shake the bottle then apply the solution to the dry hair and massage in, from root to tip ensuring the entire scalp and all the hair are coated with the solution. Leave on hair for 10 minutes. After 10 minutes comb through the hair thoroughly using the comb provided. Once you have finished the treatment, wash out the solution using an ordinary non-conditioning shampoo. Using a conditioner is not necessary. Repeat above steps on day 7 and/or 14 as required.
