A: Yes. All Tricholoy+ products are developed and manufactured in Los Angeles, California, formulated in collaboration with an expert cosmetic chemist. We use Good Manufacturing Practice (GMP) standards throughout production.

A: Yes. All Tricholoy+ shampoos and hair care products are 100% sulfate-free. Sulfates (like sodium lauryl sulfate) strip the scalp's natural oils, which can worsen hair thinning over time. We use gentle, effective cleansing agents instead.

A: Oleanolic acid is a plant-derived compound found naturally in olive leaves and other plants. Studies suggest it may help inhibit the enzyme 5-alpha reductase, which is linked to DHT-related hair thinning. We include it in our Volumizing Shampoo as a science-backed active ingredient — not a filler.

A: Biotin (vitamin B7) plays a role in keratin production — the protein that makes up hair strands. While dietary biotin deficiency is rare, topical biotin application is widely used in hair care formulations to support strand strength and thickness. Our formulas use biotin as a functional active, not a marketing ingredient.

A: It means we publish every ingredient we use and explain in plain English what it does and why it's in the formula. We don't use proprietary blends that hide what's inside. If an ingredient isn't doing something meaningful for your hair or scalp, it's not in our products.
