Bleach is a powerful chemical that can be used to lighten the color of hair. It works by breaking down the melanin in the hair, which is the pigment that gives hair its color. However, bleach can also damage the hair shaft, which can lead to breakage and hair loss.
How does bleach damage hair?
Bleach works by opening up the hair cuticle, which is the outer layer of the hair shaft. This allows the bleach to penetrate the hair shaft and break down the melanin. However, opening up the hair cuticle also makes the hair more vulnerable to damage.
Bleach can damage the hair shaft in a number of ways, including:
- Protein loss: Bleach can damage the proteins in the hair shaft, which can make the hair weak and brittle.
- Bond breakage: Bleach can also break the disulfide bonds that hold the hair shaft together. This can make the hair more likely to break.
- Moisture loss: Bleach can also strip the hair of its natural oils and moisture. This can make the hair dry and frizzy.
Can bleach cause hair loss?
Yes, bleach can cause hair loss. If bleach is used too often or for too long, it can damage the hair shaft to the point where it breaks off. This can lead to thinning hair and bald spots.
