✱ The verdict
Why it scores
8.5 out of 10
Technically an oil rather than a water-based serum, Mielle earns its place through popularity and its role in scalp-care routines.
Rosemary and peppermint oils combine with castor, jojoba, coconut oil, biotin and vitamin E. Think of it as scalp conditioning and breakage support, not a substitute for clinically established hair-loss treatments.
