Squalane for Hair
The same lightweight oil that works on skin tames frizz and adds shine to hair — without weighing it down. Here's how to use it.

Squalane isn't just a face oil. Its lightweight, fast-absorbing texture makes it a genuinely useful hair oil — it smooths the cuticle, tames frizz, and adds shine to dry ends without the heavy, greasy feel of many hair oils. Because it's the same molecule you'd use on skin, one bottle covers both.
How to use squalane on hair
- Frizz and shine: warm one to two drops between your palms and smooth over dry ends and flyaways.
- Heat protection helper: a light layer on ends before styling adds slip (it's not a substitute for a dedicated heat protectant).
- Scalp: a small amount can soften a dry, flaky scalp — go sparingly and keep it off the roots if your hair is fine.
- Overnight: a little on the ends before bed for extra conditioning.
Less is more with hair. Start with a single drop — squalane is light, but any oil in excess will weigh hair down. Build up only if you need to.

Frequently asked questions
Is squalane good for hair?
Yes. It smooths the cuticle, controls frizz, and adds shine to dry ends while staying lightweight, so it doesn't weigh hair down the way heavier oils can.
How do you use squalane on hair?
Warm one to two drops between your palms and smooth over dry ends and flyaways. Use it sparingly — a little goes a long way, and too much will make hair look greasy.
Can you use squalane on your scalp?
A small amount can help a dry, flaky scalp, but use it sparingly and keep it off the roots if your hair is fine, since any oil can leave fine hair looking limp.
