When it comes to keeping tresses hydrated, no rinse products such as leave in conditioner and hair moisturiser are popular choices. However, they have different formulations and have different use.

It is used for conditioning hair and to keep it supple for easy styling. Some products have strengthening or heat-protecting properties. It is also lighter compared to hair moisturisers.
It can be applied on dry or wet hair to keep it hydrated and supple. Some formulations may be dense so check which is specially formulated for your hair type. It is used to retain moisture in thick, dry hair. Apply as needed until the next washing. This is best for thick, curly hair strand as it can weigh down hair.
