Overview
A humid climate is where this conditioner earns its place, detangling frizzy hair and smoothing it with camellia oil and glycerin. It leaves hair soft with a radiant shine and does not weigh it down.
Easy detangling and smooth, shiny lengths are the reason to use it. Hair type and scent details are thin in this listing.
Who it's for
Wavy, curly or dry hair that knots and puffs after washing benefits most. Those with fine, flat hair who want lift should look at a volumizing conditioner.
Pros and cons
- Fights frizz and dryness
- Does not weigh hair down
- Scent not listed
- Smoothing works against volume
Performance notes
Glycerin draws moisture into dry strands while camellia oil smooths the surface, so tangles slide apart and frizz settles. A short leave-on before rinsing is enough for it to coat the lengths.
