Cosmex hair oils and serums
Oil for dry, porous lengths; serum for light care with one job.
Oil is for lengths that lack lipids: it smooths the cuticle, adds shine and makes combing easier. A serum is lighter than oil and does one job — split ends, shine or care for fine hair without weighing it down. Scalp care is a separate group: rosemary oil and the activator serum go on the roots, not the lengths.
Frequently asked questions
Do I apply hair oil before or after washing?+
On the lengths — 2–3 drops after washing, on damp or dry hair, mid-lengths to ends. Rosemary oil for the scalp goes on 30–60 minutes before washing and is rinsed out with shampoo.
Serum vs oil?+
A serum is a light leave-in formula for one task and does not weigh fine hair down. Oil is richer and suits dry, porous lengths better.
Can I use these oils on my face?+
Argan, jojoba and squalane are multi-use — for hair and facial skin, as stated in the product name.
