How Often Should A Man Have A Conditioning Treatment Put On His Hair? Is It At All Necessary? Will It Help Prevent Hair Loss?

 Hi David.

It is important for men to use conditioner. Shampoo opens the hair’s cuticles and conditioner closes them.
Using any conditioner will not help with hair loss.
There are professional products that do help with hair loss though, such as Nisim NewHair Biofactors. They are the leaders in sorting out thinning hair.
