Hair splitting should be found to reduce the frequency of perming, dyeing and blow-drying, try not to use strong alkaline shampoo to wash hair, and the water temperature should not be too high when washing hair.
Cut off the longitudinal part of the end of the hair and the normal-looking hair about 2cm from the split ends.
Use a wooden or horn comb to neaten the hair flow every day to help distribute the oil evenly throughout the hair.
For dry hair, apply a good quality vegetable oil or olive oil to the split ends and rub down the entire hair, then separate the strands so that all the hair is saturated with the warm oil, massage the hair and keep the oil for a period of time so that it is fully absorbed.
Dry hair is more prone to tangles, shampoo it soothingly and let the water rinse it out, dry the hair and comb it thoroughly through with a wide toothed wooden comb.
