Oil‑in‑serum hair treatments offer shine without heaviness
Experts say oil‑in‑serum treatments give the moisture and smoothing of oil in a lighter, easier‑to‑apply serum format.
By Felo News Desk · Published
Dermatologists and hairstylists have highlighted oil‑in‑serum hair treatments as a hybrid option that delivers the nourishing benefits of oil while keeping hair light and non‑greasy. According to Dr. Alexandra Bowles, a board‑certified dermatologist at MONA Dermatology, the formula coats the hair fibre, smoothing the cuticle and locking in moisture without the heaviness of a traditional oil. Hairstylist Kee Taylor adds that the product can reduce friction during styling, which helps prevent breakage and split ends.
How the treatments work
Oil‑in‑serum blends oil and serum ingredients, creating a protective layer that improves softness, shine and manageability. Both experts recommend starting with a small amount and increasing only if needed, warning that over‑application can be difficult to remove. The products can also contain antioxidants and heat protection, according to Bowles.
Which hair types benefit most
While the treatments work on all textures, Taylor notes that fine or straight hair should use a lightweight serum in small quantities, whereas curly, coily or thick hair can tolerate richer formulas. Chemically treated or heat‑damaged hair may also gain from the added conditioning.
Using the product
Both Bowles and Taylor advise focusing on mid‑lengths and ends rather than the scalp, especially for oily hair. The instructions on the specific product should guide whether to apply to damp or dry hair, and whether heat tools are used.
