Many people will put "moisturizing and hydrating" on their lips "hydrating and moisturizing, foolproof", but many people only pay attention to facial skin replenishment, but they don't know that scalp skin care is also a must-do beauty practice, is scalp hydration really so important?
The secret of a dehydrated scalp
The shampoo is over-degreased
Normally, the pH of our scalp is in the (4.).5~6.5) intervals, showing weak acidity. If we use a washing product with strong degreasing power (pH value greater than 7) for a long time, it will lead to further lack of water and oil in the mucous membrane of the head, and the sebaceous glands will secrete more oil in order to protect our scalp, resulting in more oily hair!
Seasonal changes
In summer, excessive exposure to sunlight can easily burn the scalp due to strong ultraviolet rays, and the surface of the hair cortex will become very rough, and the hair will be damaged and dry, making it difficult to comb.
In winter, when the temperature drops and the temperature changes greatly, the scalp will become dry, and the water will not be replenished in time, resulting in a decrease in sebum secretion and hair dryness and shedding.
Gender age differences
Studies have shown that the water content of the stratum corneum at the top of the scalp increases with age, while oil production decreases with age. Moreover, the scalp is not only affected by age, but also by gender: male hormones are higher in men than in women, and the secretion of sebaceous glands is more vigorous, resulting in a more oily scalp.
What are the symptoms of dehydrated scalp?
Hair is fragile and prone to hair loss
The hair is frizzy and the cuticle is open, which is very easy to absorb dust and bacteria in the air, making the hair sensitive and brittle, and easy to break. Especially in autumn and winter, the dry season can easily break the water and oil balance of the hair, leading to hair loss.
Hair static electricity worsens
When the hair is dry and dehydrated, it is also easy to produce electrostatic friction, and the drier it is, the more obvious it is, especially when wearing sweaters and down jackets in autumn and winter, it is particularly obvious, and occasionally you will hear sizzling sounds, indicating that your scalp is seriously dehydrated.
