Does sodium hydroxide make hair fall out?

Yes, sodium hydroxide can cause hair loss. Sodium hydroxide is a strong alkali that is often used in hair relaxers and other hair products. It can damage the hair shaft, causing it to become weak and brittle. This can lead to hair breakage and hair loss. Additionally, sodium hydroxide can also irritate the scalp, which can also contribute to hair loss.

If you are experiencing hair loss, it is important to see a doctor or dermatologist to determine the cause and get the appropriate treatment.
