Avoid chemical based shampoo, conditioner and styling products. Most hair products contain chemicals that are effective at cleaning your hair but may cause much damage. Some people aren't affected by these chemicals, but if you're worried about thinning hair, it's best to avoid them.
Sodium laurel and laureth sulfates are cleaning agents found in most shampoos. They strip the hair of natural oils and cause hair to weaken and fall out over time.
Choose organic products or products made with natural oils and soap agents. Check www.thegoodguide.com for detailed information about different hair products and which ones are better to use for those concerned about hair loss.
