Keratin hair treatments promise sleek, shiny hair, but they can come with unexpected side effects. From hair damage to respiratory issues, it's important to understand the potential risks before getting the treatment.

Damage To Hair

Keratin treatment only causes hair to become brittle or break due to the incomplete processing of chemical elements in the hair.

Irritation of the Scalp

Formaldehyde is just one of the chemicals in keratin treatments that can irritate the scalp and cause itching or redness.

Thinning Hair

Frequent keratin treatments make hair weak and may eventually thin because hair strands are more likely to break.

Allergic Reactions

Many people suffer from being allergic to the common chemicals found in keratin treatments which cause swelling, rashes, or even just breathing difficulty.

Change in Hair Texture

Enhancing a straightened appearance, keratin treatments change and restrict hair to its original structure.

Irritation of the Eyes and the Respiratory System

Fumes from keratin treatments, especially that of formaldehyde, can cause a person to experience much irritation in the eye, cough, and even respiratory problems.
