Reduce Shampoo Use
when the cool autumn comes or in the warm evening of winter, under the huge temperature difference in thermal expansion and contraction of extreme environments, hair becoming dry is very common in this season, we must focus on treating the hair carefully during this period.
In general, many people think that hair care is a simple. In fact, they are wrong. whether it is oily hair or dry hair, using shampoo and conditioner too often can not keeping hair well, but will cause more hair damage!
The reason is as follow:
① Our hair is actually divided into three levels: epidermis, cortex and medulla! The outermost layer of the hair is the epidermis. they cover the hair from root to the tail. They can protect the hair against external mechanical damage.
② cortex (CORTEX):underneath the epidermis, made of the protein cells and pigment cells, is the subject of hair. It containing salt, sulfur string, fibrous cortical cells, giving the hair elasticity and toughness. Physical and chemical effects are attributed to this layer of hair. Hair pigment particle layer also determines the hair colors.
③ medullary layer (MEDULA): at the center of the hair. Not all hair has hair marrow. It has no much effect on the hair properties.
The cuticle of hair is open shape. During shampooing with warm water or alkaline substances, the hair cuticle will swell. Cortical layer lose water rapidly from the hair cuticle gap, so drying hair with high temperature or dying process may cause hair lose water easily, hair will become dry and frizz!
Even you use hair extensions such as pre bonded hair extensions or human hair micro loop hair extensions , you still need to be careful, don’t use high temperature to drying it, dye it or use too often shampoo on it. Treat your human hair extensions the same as your natural hair.
