Overview

Smoothing this biotin conditioner through thin hair after washing adds shine and softness while protecting volume. R+Co blends pro vitamin B and coconut oil with loquat fruit extract and a warm cardamom, tangerine and lavender scent.

Thin hair often goes flat under rich conditioners, and this one aims for hydration without the drag. Bottle size is missing from the listing, which makes comparing quantity impossible.

Who it's for

Fine hair washed with a volumizing shampoo pairs well with it, since both aim for body. Coarse, damaged hair may need a heavier mask.

Pros and cons

Pros
  • Light enough for thin hair
  • Vegan, paraben and gluten free
  • Warm, layered scent
Cons
  • Bottle size not listed
  • Strong scent may not suit all
  • Light conditioning for dry hair
  • Directions not given

Performance notes

Conditioners for fine hair use lighter emollients that smooth the cuticle without coating heavily, so strands stay separate and lifted. Keeping it to mid-lengths and ends avoids weighing down the roots. Pro vitamin B helps hair hold moisture, which shows as shine.
