This  set includes one shampoo and one conditioner bar.  These bars have no lye and are ph-balanced and are geared toward gray or aging hair.  Signs of aging hair include turning gray because lack of pigment, thinning hair, the texture is course and wiry, and the appearance is dull and dry.  
I have made these shampoo and conditioner bars to help with these issues by adding mango butter which contains Oleic Acid which strengthes the hair follicle  and promotes hair growth.  The creamy consistancy of mango butter helps  it form a protective coat over the hair strands and fortifies it against breakage and split ends.
Argon Oil has antioxidants that repair damage to the cellular membrane.  It contains vitamin E whose function is to bring back imperfect hair by repairing cuticle and treating brittle hair.
Essential Oiils: Chamolile prevents premature aging of the hair, Clary Sage slows down the rate at which the hair follicle ages and promote blood circulation to the scalp, Rosemary promotes hair growth,Lavender balances the scalp and Peppermint helps with blood flow to the scalp to nourish the hair. 
The conditioner bar adds to shampoo bar with Keratin, Aloe Vera, Honey Quat and Silk Amino Acids they add softness and a silky feel to the hair.
These Syndet bars last 60 to 65 shampoos  and the shampoo bar is 2.25oz and the conditioner bar is 1.50oz.
