When conditioner isn't enough. The intensive weekly treatment for hair that's been through it.
Chlorine, hard water, heat styling, sun exposure, and daily friction degrade the hair's keratin structure over time. Each strand loses protein, becomes more porous, and breaks more easily. Regular conditioner maintains it doesn't rebuild. When damage has accumulated to the point where your hair feels dry, rough, and snaps when you comb it, you need a treatment rather than maintenance.
The Keratin Intensive Rescue Hair Mask delivers concentrated hydrolysed keratin and argan oil into the hair shaft during a 5–10 minute treatment window. Keratin fills the structural gaps where protein has been lost. Argan oil seals the cuticle and restores the shine that damage strips away. Panthenol adds moisture to the cortex so repaired hair stays flexible rather than brittle.
Use once a week in place of your regular conditioner. Leave on for 5–10 minutes. Rinse. The difference is immediate, and it compounds with weekly use.
