Mielle states this suits all hair types and textures, 3A through 4C curl patterns, including chemically treated and color-treated hair. It's a mass consumer-retail product (also sold at Target and Walmart), not a salon-exclusive line, so no professional-only restriction applies — anyone can pick it up and use it at home.

If you're dealing with coarser, coilier, or chemically treated hair that tangles easily and doesn't hold moisture well, the heavier cationic-conditioner-plus-oil combination here is built to handle exactly that, which is more than a lightweight conditioner made for finer hair textures would offer.

After shampooing with Rosemary Mint Shampoo, apply to damp hair and gently detangle with a wide-tooth comb for even distribution. Leave on for 5 to 10 minutes, then rinse thoroughly. Follow with Rosemary Mint Strengthening Leave-In Conditioner.

The cationic conditioners plus the shea/avocado/coconut/olive oil blend are a real, mechanistically sound combination for detangling and sealing in moisture on coarser or coilier textures, which is where this line is clearly aimed. The free-from claims (no parabens, sulfates, paraffins, mineral oil, or DEA) are genuine and verifiable.

The one claim worth tempering is biotin as a 'strengthening' ingredient — most research on biotin and hair strength involves oral supplementation for people who are biotin-deficient, not a rinse-out conditioner, so treat that specific benefit as a supporting ingredient rather than a guaranteed result. It also contains fragrance and essential oils (rosemary, peppermint) that can be sensitizing for reactive scalps.
