BASED Shampoo
At a glance
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.

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

Olive-derived plant emulsifier (component of Olivem 1000); pairs with Cetearyl Olivate for a biomimetic emulsion. Replaces PEG and silicone-based emulsifiers.
See more about Sorbitan Olivate →Hydrolyzed KeratinVery 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.

Lipid-soluble antioxidant that stabilizes oils in the formula and protects skin lipids from oxidative damage. Synergistic with most plant oils.
See more about Tocopherol (Vitamin E) →Avocado OilVery 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.
See more about Avocado Oil →Argan OilVery 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.
See more about Argan Oil →Peppermint OilVery 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.

Humectant that draws moisture to the skin — a beneficial base ingredient.
See more about Glycerin →Coconut OilGood
Source of medium-chain lauric acid with documented antimicrobial activity against acne-relevant skin bacteria; clean emollient base.
See more about Coconut Oil →Aloe VeraGood
Acemannan polysaccharides -- anti-inflammatory and hydrating; long clinical track record.
See more about Aloe Vera →Potassium Sorbate + Sodium BenzoateGood
Food-grade preservative pair; EWG 1-3, the cleanest broadly-effective system available. Replaces phenoxyethanol.
See more about Potassium Sorbate + Sodium Benzoate →ArginineGood
Amino acid; functions as a buffering pH adjuster and contributes minor humectant activity. Inert at use levels.
See more about Arginine →Guar GumNeutral
Plant-derived thickener, generally well tolerated.
See more about Guar Gum →Citric AcidNeutral
Common acidulant and preservative — safe at typical use levels, neither beneficial nor harmful.
