Does getting hair smoothing treatments harm the body?

Smoothness usually refers to smooth hair. Generally, hair smoothing treatments can cause certain harm to the body, such as skin irritation and itching, disruption of the scalp's natural oil balance, hair damage, and hyperpigmentation. The specific effects vary from person to person. It is recommended to avoid frequent or long-term hair smoothing treatments to prevent adverse impacts on health.

Health risks associated with hair smoothing:

1. Skin irritation and itching

Chemicals in hair smoothening agents—such as ammonia and hydrogen peroxide—may cause scalp itching and redness when they come into contact with the skin. For individuals with sensitive skin, this irritation may be more pronounced and could even lead to allergic reactions on the scalp, including rashes or blisters.

2. Disruption of the scalp's oil balance

Hair smoothing treatments may over-cleanse the hair, stripping away excessive natural oils. This can deprive hair of its natural protective and moisturizing functions, leaving it dry and brittle.

3. Hair damage

Hair smoothing processes typically involve chemical agents like smoothing solutions. These chemicals alter the internal structure of the hair and damage the cuticle layer—the outer protective layer of the hair shaft. Once damaged, the hair becomes dry, weak, and prone to breakage.

4. Pigmentation (hyperpigmentation)

During hair smoothing treatments, chemical agents may irritate the scalp and surrounding skin, causing inflammation. Inflammatory responses can stimulate melanocytes (pigment-producing cells) in the affected area, increasing their activity and potentially leading to darkened skin patches.

Hair Smoothing Treatment Overview:

In daily life, it is advisable to regularly trim hair ends to remove split ends and frayed tips. Choose a shampoo suitable for your hair type and avoid products containing excessive chemicals to minimize potential hair damage.
