If frizz is your daily battle, a leave-in conditioner is one of the most useful products you can own — it seals moisture in and humidity out, which is exactly what frizzy hair needs. Here's how to choose one that works for your hair rather than weighing it down.
What a good leave-in does
- Seals the cuticle so humidity can't swell the strand (the root cause of frizz).
- Hydrates and detangles without rinsing out.
- Adds slip and softness, making styling easier and gentler.
- Protects — many double as light heat/UV protection.
How to choose for your hair
| Your hair | Best formula |
|---|---|
| Fine / oily-prone | Lightweight spray leave-in |
| Medium | Light lotion |
| Thick / coarse | Richer cream |
| Curly / Afro | Cream with more moisture + definition |
Ingredients to look for: humectants (glycerin, panthenol) to draw in moisture, plus a little oil or silicone for slip and sealing. Go easy on heavy butters if your hair is fine.

How to apply it

- Style as usual — add a couple of drops of argan oil on the ends to finish.
