Skills of nursing and repairing hair after perm and dyeing;

1, shampoo and conditioner?

After dyeing, the hair scales in our hair are already in a semi-open state, and using alkaline shampoo can only make it excessively open. The hair conditioner we usually use is generally acidic, which closes the hair scales, so we will feel that the hair is very supple after use, but it is only temporary.

Therefore, when shampooing, choose a shampoo with good quality and low alkalinity, and then use conditioner to maintain it, so as to keep the hair soft, fluffy and bright, and increase the firmness of the hair.

2. Do you oil regularly?

It's best to do an oil-baking treatment for your hair once every other month. During the oil-baking treatment, apply the oil-baking ointment evenly on your hair and keep your hair in a fluffy and natural state.
