hair growth cycle
The hair growth cycle is 2 to 7 years, which is divided into a growth period, regression period and rest period. The growth rate of hair is related to the season and climate. The growth period is 2 to 7 years. After the hair grows to 40 cm, the growth rate is slow and the regression period is only 2 to 4 weeks. This means that people have new hair growing every day, as well as hair loss. For Asians, there are 3 to 4 hairs in a follicle. The resting period is 3 to 4 months. In these 4 months, hair grows very, very slowly. New hair then grows from the follicle. Many people are troubled by the hair, which affects the mood of the day.
There are many reasons for hair loss.
1. Pregnant mothers will experience a lot of hair loss during pregnancy, because pregnancy, eating a lot of supplements, and excessive stress, will also cause hair loss. (during pregnancy, postpartum baby, breastfeeding period, static perm and dyed hair, use separate shampoo). There will also be a lot of hair loss after giving birth, natural reaction, metabolism, so don’t worry.
2. Seasons and climate change. The scalp is the same as the skin. When the season changes, the skin is dehydrated, and the scalp is also dehydrated. The dehydration of the scalp leads to hair loss.
3. High work pressure, irregular life and staying up late can also lead to hair loss.
4. Excessive ironing and dyeing, using shampoos with high alkalinity, or shampoos containing a lot of chemical ingredients, everyone knows that washing clothes contain a lot of alkalinities, and washing clothes will feel tingling when they touch the skin. The same goes for the scalp. Alkaline shampoos can irritate the hair follicles, causing the follicle cells to grow larger and causing a lot of hair loss.
5. Replace shampoo: skin and scalp will be dependent. Choose a good shampoo. Make you happy every day. Hair is a person’s second skin and also a person’s second face, so protecting your own image starts with choosing a shampoo.
