1. What are the five major scalp problems?
Generally, besides alopecia caused by alopecia, scar and alopecia areata, other scalp problems are mostly caused by the following five reasons.
1, hormone disorder in the body
The amount of sebum produced by sebaceous glands is mainly determined by heredity, but it will change with the change of androgen level in the body in the later stage. Unstable hormone levels in the body will cause the scalp to produce more oil.
2, fungi, too much dandruff
When the scalp cell layer is seriously damaged, dandruff will recur, and the sparse scalp cell layer is difficult to maintain the health of hair follicles.
3. Seasonal influence
Fungal infection of scalp can cause scalp itching, and it can also be caused by insufficient cleaning or dandruff. Seasonal itching may also be an individual susceptibility problem.
4. The influence of living habits
Bad living habits will also destroy the healthy environment of the scalp, such as eating some irritating food, spicy, polysaccharide, greasy, staying up late, emotional instability and so on. Shampooing may cause scalp sensitivity, occasional rash and tingling.
5. Cumulative damage of external pollution to scalp
Cutaneous chips in scalp, components in sweat and residues of hairdressing products will all endanger the health of scalp.
Second, how should the scalp be cared for?
1, don't fall asleep with wet hair.
Sleeping with wet hair will cause a lot of water to stay on the scalp surface, which is moist and airtight, easy to breed microorganisms, cause dandruff and scalp diseases, and even cause physiological diseases such as facial paralysis.
Step 2 choose the right comb
The choice of comb material will also affect scalp health. Plastic combs are prone to generate static electricity, absorb dust and dirt, and damage hair and scalp. It is best to use natural materials such as wood and ox horn. The comb teeth should not be too sharp, which will scratch the scalp and cause inflammation.
3, keep the scalp pH balance
The normal scalp ph value is 4.5~6.5, which is weakly acidic, so whether it is weakly alkaline or acidic, it is not conducive to the hair follicle growth cycle. When choosing shampoo, you should adjust it according to the quality of your hair. If you often feel dry and itchy after washing your hair, it is probably too alkaline. You can add some white vinegar to neutralize it
4, to prevent ultraviolet damage
Because the scalp is thinner, weaker and more prone to aging than facial skin, it is vulnerable to ultraviolet rays, leading to hair loss and scalp relaxation and aging, so it is usually necessary to avoid scalp exposure in the sun.
