Matters needing attention in dyeing hair
1, choose the right hair dye: choose a good quality hair dye and read its composition and function carefully. It is best to choose a non-irritating, natural or organic hair dye to reduce the damage to the hair.
2, hair care: before dyeing, use hair care oil or conditioner to protect hair and reduce the irritation of hair dye.
3. Pay attention to the hair condition: if the hair is dry, damaged or bifurcated, it should be repaired and cared first to avoid the hair quality getting worse after dyeing.
4. Evenly apply: When dyeing hair, the hair dye should be evenly applied to the hair, especially to avoid excessive application of the hair dye to the scalp.
5, pay attention to time: hair dye should not stay in the hair for too long, otherwise it may cause damage to the hair. Generally speaking, the dyeing time should not exceed 30 minutes.
