Summary

BASED Shampoo scores 97/100 -- a premium, non-toxic shampoo with a clean cleansing system and a real conditioning payload. Zero sulfates (no SLS/SLES -- the surfactants that strip the scalp barrier in 95% of drugstore shampoos), zero parabens, zero phthalates, zero endocrine disruptors, no PEGs, no silicones, no quaternary ammonium 'quats', no phenoxyethanol, no synthetic fragrance. Independently lab tested. The cleansing agent is coco-glucoside, a sugar/coconut-derived non-ionic surfactant -- the gentlest broadly-effective surfactant class, EWG 1. Conditioning is provided by hydrolyzed keratin, four plant oils (avocado, coconut, argan, plus aloe vera juice), glycerin, and the Olivem 1000 plant emulsifier system. Peppermint essential oil supplies a single-source named scent and a real scalp-circulation benefit -- far more transparent than the 'naturally derived fragrance' disclosure used in many clean brands. Food-grade potassium sorbate + sodium benzoate handle preservation.

Cetearyl Olivate
Very Good

Olive-derived plant emulsifier (component of Olivem 1000); biomimetic to skin lipids, gentle on the barrier, replaces PEG and silicone-based emulsifiers.

Hydrolyzed Keratin
Very Good

Enzymatically broken-down keratin protein fragments small enough to penetrate the hair cortex and bind to damaged sites. Genuine repair activity (Wickett 1991), not just superficial coating like silicones.

Tocopherol (Vitamin E)
Very Good

Lipid-soluble antioxidant that stabilizes oils in the formula and protects skin lipids from oxidative damage. Synergistic with most plant oils.

Avocado Oil
Very Good

Source of monounsaturated fatty acids (oleic acid), Vitamin E, and beta-sitosterol; penetrates the hair cortex (one of the few oils that does, alongside coconut and olive) and reduces protein loss during washing.

Argan Oil
Very Good

Cold-pressed from Argania spinosa kernels; rich in oleic and linoleic fatty acids plus tocopherols and squalene. Penetrates the hair cuticle and reduces protein loss.

Peppermint Oil
Very Good

Single-source named essential oil -- fully transparent compared to 'naturally derived fragrance' listings. Menthol provides cooling sensation and stimulates scalp circulation, with a small RCT (Oh 2014) showing increased follicle depth and density at 3% topical application.
