Each year, Americans spends millions of dollars on hair-care products and treatments. Unfortunately, some of these efforts are too rough or done frequently. The result is hair damage rather hair care.
Damaged hair stays damaged until it grows out and is cut off.
Hair gets dirty when sebum, an oily substance secreted by the skin's sebaceous glands, coats the shaft. Dead skin cells and airborne dirt stick to the sebum. Rinse water carries the micelle away. Coloring, perming, combing, teasing and shampooing can break the cuticle's long protein chains. The cuticle gets shaggy, and hair becomes rough.
