On whether it is feasible to leave fruit acid on the scalp overnight
The fruit acid has a long-standing reputation in the field of skin care and has a wide range of effects, such as exfoliating, rejuvenating the skin, promoting circulation and enhancing luster, which is much praised by the world. However, if it is applied to the scalp and left overnight, the advantages and disadvantages are geometric, and it needs to be reviewed in detail.

The scalp, an important part of the skin surface of the human body, has unique characteristics compared with other skin. The stratum corneum of the scalp is slightly thicker than the facial skin, but the hair follicles and sebaceous glands are densely covered, and the physiological activity is vigorous. The nature of fruit acid is corrosive to a certain extent. Although it can loosen the connection between keratinocytes and promote the shedding of old keratin, factors such as concentration and duration of action are all related to whether the scalp can tolerate it.

If the low concentration of fruit acid, its effect is mild, or it can clean the keratin of the scalp, help the hair follicles to be unobstructed, and is beneficial to the improvement of the scalp environment. Leave it overnight, or it can gradually exert its effect and promote the normalization of keratin metabolism. However, if fruit acid remains in the scalp for too long, there is also a risk. The natural barrier function of the scalp may be damaged due to the long-term action of fruit acid. If the barrier is damaged, external stimuli are easy to invade, causing the scalp to be sensitive, and itching, tingling, And the ecological balance of the microbial community of the scalp may be damaged, and the microbial imbalance may easily lead to various scalp diseases, such as seborrheic dermatitis and increased dandruff.

In addition, individual tolerance to fruit acid varies widely. People with sensitive skin have delicate scalp. Even if low-concentration fruit acid is left overnight, it may be intolerant and have a strong reaction. Those with strong tolerance, although they may be able to bear it, should not be taken lightly. If you do this for a long time, latent risks remain.

To sum up, if you want to leave fruit acid on the scalp overnight, you must be cautious. Do a local skin test first to see if there is any discomfort. And you should consult a professional, weigh the pros and cons according to your scalp condition and skin characteristics, and choose the most suitable method. Do not act rashly, so as not to damage the health of the scalp and regret it.
