Someone has told me that nexus biotin shampoo works great for hair fall. I was searching on net and I found different hair shampoo of nexus biotin like nexus vita tress biotin thickening shampoo, nexus 3 vita tress biotin shampoos for fine hair, nexus vita tress biotin shampoo for thinning hair and more⦠I want to know as I am looking for the shampoo which can protect my hair fall, which shampoo I should go for, Nexus vita tress biotin thickening shampoo or shampoo for thinning hair. I am not able to differentiate between the two and want to know from anyone who can understand my confusion and tell me the right way out.
