The scalp and hair are very closely related, but the problems encountered by the scalp and hair are different. Generally speaking, hair problems are mostly manifested in the aspects of fine and soft hair, dry hair, split ends, inelasticity, damage, and easy breakage. Scalp problems are mostly manifested in greasy scalp, dandruff, sensitive scalp, and hair loss.
First of all, let's understand the hair problem. There are three stages of hair: growth phase, regression phase and resting phase. There are about 100,000 hairs per person, and the life span of hair is 2 to 7 years. Of all human hair, the hair in the growth phase accounts for 85-90%, the hair in the catagen phase accounts for 1%, and the hair in the resting phase accounts for 9-14%. . The hair in the telogen phase will fall off when washing, combing, or scratching the hair. In normal times, after three months, a hair will grow again in the same place.
However, when the hair follicles shrink, the hair becomes shorter and thinner, leading to hair loss, and in severe cases, the complete death of the hair follicles can cause permanent baldness. Intrinsic factors Simple rinse when shampooing; irregular diet, frequent drinking, eating irritating food; excessive sebum secretion on the scalp. Excessive sebum mixed with dust and other things will form dandruff after the hair dries; poor sleep quality and aging of the scalp.
External factors use hairdressing products containing silicone oil and sulfate; use some inferior shampoos with strong degreasing power; Intrinsic and extrinsic factors are the root causes of hair problems. If you want to completely solve the problems above the head, you need to start from two aspects, internal factors pay attention to life adjustment; external factors pay attention to choosing the right hair care products.
Pay attention to frequent shampooing and massage, dry your hair naturally, eat a comprehensive diet, eat more raisins, black sesame, ginger, walnuts, almonds, carrots, etc., maintain a happy mood, use your brain moderately, and maintain adequate sleep. :.
