Expert Reviews


What reviewers liked

Excellent benefits when used in dry or wet hair: this is absolutely my favorite hair oil and it completely changed my hair, which is soft, smooth, and silky after use. Can be used in wet or dry hair: while I personally prefer using this with wet hair which can hold in more moisture, but it can also be used for a sleeker in dry hair after styling. Suitable for all hair types, including straight, wavy, curly, coiled, or tightly coiled, and safe for keratin-treated hair. Has a lovely gardenia and violet scent devoid of any harsh perfume odor or artificial quality. Multi-use benefits: product also protects from future heat damage from styling tools, as well as UV damage. Formulated free of any parabens, sulfates, or harsh chemical additives.
It also protects hair from heat and UV damage, and keeps color-treated strands looking healthy and vibrant. It's formulated without harmful additives like sulfates, parabens, and phthalates, and it's even cruelty-free. The bottle is small enough to travel with, and to top it all off, the oil works on all hair types and textures.
It worked for my fine hair. It is neither too slippery nor too greasy. The scent though strong, does not bothers me. I find it pleasant. It helps tame the frizz and smooths the hair. I like to use flat iron after applying this and the combination of the two gives soft, smooth, silky manageable hair.

What reviewers didn't like

Price: definitely the only con I’ve found in using this is the price tag, as $28 is rather steep for a hair oil. Scent is lovely but it would be nice if it lingered for a longer time after use.
