Anyone whose hair frizzes, tangles or turns dull, and who wants a light leave-in rather than a heavy cream. UANS singles out permed and naturally curly hair, where it helps restore bounce. It is a retail product that is simple to use at home, and stylists use it as a blow-dry prep.

Revita sits between a conditioner and a styling aid. One pump through towel-dried hair smooths the cuticle so hair dries faster and shinier, and the light hold keeps frizz down once it is dry. For perms and natural curls it gives back spring without the crunch of a gel, and because it is so light it can be reapplied on dry hair to settle flyaways during the day.

1. Shampoo and condition, then towel-dry.
2. Apply sparingly through damp hair, paying particular attention to the ends.
3. Do not rinse. Style as usual.
4. May also be applied to dry hair.

Pros:

• Light enough to use daily without weighing hair down
• Cuts blow-drying time and gives some protection from styling tools
• Works on damp or dry hair
• 600 ml refill pouch to top up the pump bottle

Cons:

• Contains alcohol, so very dry or brittle hair may want a richer leave-in
• Not a dedicated heat protectant for high flat-iron temperatures
• Fragranced
