Hair boss
I shampoo my hair everyday and whenever I tell people that, they stare at me with a look of disbelief and jovially say, "You're going to become bald!"
So, I went on a little treasure hunt to figure out what's going on
I'll outline what I've found. Shampooing CAN damage hair. Only damage hair, not directly cause hair loss. Sodium Lauryl Sulfate, the main surfactant in most shampoos is the main problem. STS causes skin irritation. This is proven. But only in high concentrations and not for everyone. Irritation can cause inflammation which in turn can be linked to hair loss. Tests and research are all highly inconclusive. Irritating!
If you find you're losing hair during shampooing. It's normal. Hair that is weak is ripped out due to the chemicals.
So, is shampoo good or not? I'll shoot now. It depends! For some people, even a little shampoo can screw their hair life. For others daily hair wash is fine (like me). It's very important to find shampoo that suits your hair. Its different for everyone. Anti dandruff shampoos are very strong. This is all common sense of course.
Another problem I must address is how to use shampoo. Turns out the correct way to shampoo is to apply a small quantity to your palms first and do a preliminary washing sequence. Then apply another small quantity, massage into the scalp thoroughly and wash very thoroughly (I'll try to reference this). STS cleans by destruction. Get it out fast. It cleans up pretty soon.
Another amusing piece for me: Oiling hair does not improve hair. So much for all that Indian female talk about oiling one's hair! Oil only conditions the scalp. Nothing else. Largely unconnected with hair growth.
