This treatment is aimed at anyone with dry, moisture-starved, or coarse hair that needs a periodic deep-conditioning boost rather than a light daily conditioner. It works on color-treated hair as well.

It's a rinse-out mask, not a leave-in, so it suits people willing to add a 3-5 minute treatment step to their routine occasionally (Paul Mitchell recommends weekly), rather than those wanting an everyday, quick-rinse conditioner.

The differentiator here is the moisture-and-protein pairing — spirulina and Irish sea moss extracts alongside hydrolyzed soy protein — rather than an occlusive oil-heavy mask base. That combination is aimed specifically at hair that's dehydrated and tangle-prone rather than hair that's missing lipids or oils, so it detangles and softens without leaving a coating behind. Used as the brand intends, as a periodic reset rather than a daily step, it's a targeted moisture treatment more than a general-purpose conditioner replacement.

Apply after shampooing, to clean, towel-dried, damp hair, working it evenly from mid-lengths to ends. Paul Mitchell recommends using it weekly as a treatment rather than daily.

• Shampoo and towel-dry hair
• Apply a generous amount from mid-lengths to ends
• Leave in for 3-5 minutes
• Rinse thoroughly
• Repeat weekly rather than with every wash

Pros:

• Marine-derived spirulina and Irish sea moss extracts plus hydrolyzed soy protein target moisture and softness without a heavy oil or silicone base
• Lightweight enough to rinse clean rather than sitting on strands, so it works as an occasional deep treatment without weighing hair down
• Safe for color-treated hair

Cons:

• Not a daily-use product despite the name — using it every day isn't how Paul Mitchell recommends it, and won't necessarily add benefit over a regular conditioner
• Contains the preservative combination methylchloroisothiazolinone/methylisothiazolinone, which can be a scalp irritant for sensitive-skin users
• Contains added fragrance (including hexyl cinnamal, limonene, geraniol, citronellol), so it isn't fragrance-free
