Hair Rejuvenating Cream Treatment contains:

Linum usitatissimum is an plant of the linaceae family with several biological properties such as an indirect effect on hair regrowth through. These results suggest that flax-seed oil has some hair growth promoting potential. Benefits: these amino acids have regenerating and strengthening properties for the hair.

Hydrolysed silk
Like no other protein, hydrolysed silk protein improves the shine of the hair, adds to the elasticity of the hair to prevent breakage and helps the hair retain moisture for longer periods of time.

Macadamia oil
Dry, damaged hair follicles can be treated, but it is equally important to treat the scalp so that new growth may be possible. Macadamia oil’s acid content controls oil production and promotes skin regeneration.

Cetearyl Olivate
A nonionic emulsifier that helps blend ingredients together in cosmetic solutions, usually ones with moisturising properties. It’s helps soften the skin & hair.

Sorbitan Olivate
Sorbitan Olivate is a surfactant and emulsifier made from olive oil and sorbitol (a natural sugar alcohol). It is biodegradable, non-toxic and a non-irritant.

Vitamin E may help support a healthy scalp and hair as it has natural antioxidant effects that could assist with maintaining hair growth. The vitamin’s antioxidant properties could help reduce the amount of oxidative stress and free radicals that cause the hair follicle cells in a person’s scalp to break down.
