Hair masks and hair spa treatments both promise softer, smoother, healthier-looking hair, so what is the difference, and do you need both? Here is a simple guide.
What is a hair mask?
A hair mask is an intensive conditioner. It has a richer formula than a regular conditioner and stays on the hair for longer, usually 5 to 15 minutes, so the nourishing ingredients have time to work. Keratin masks are especially good at smoothing the hair surface, taming frizz and restoring shine.
Best for: regular at-home care, frizz control, keeping keratin-treated hair smooth, and quick weekly nourishment.
What is a hair spa?
A hair spa is a deeper treatment ritual, traditionally done in salons. It usually combines a nourishing cream with a gentle massage and, in salons, steam. The aim is deep conditioning and repair, plus a relaxing experience. With a salon-formula product like the Kerasis Keratin Hair Spa, you can recreate this at home.
Best for: very dry or damaged hair, a weekly pampering ritual, and salon hair spa services.
Mask or spa: which should you choose?
- Your hair is frizzy or keratin-treated: a keratin hair mask once or twice a week keeps it smooth and shiny.
- Your hair feels very dry, rough or damaged: start with a hair spa treatment once a week for deeper nourishment.
- You want the best of both: alternate between them, for example a mask mid-week and a hair spa at the weekend.
How to do a hair spa at home
- Shampoo with a sulfate-free shampoo and gently squeeze out excess water.
- Apply the hair spa cream from mid-lengths to ends, and massage gently for a few minutes.
- For extra effect, wrap your hair in a warm, damp towel.
- Leave on for 10 to 15 minutes, then rinse thoroughly with lukewarm water.
- Finish with a few drops of serum on towel-dried hair.
Whichever you choose, always start with a gentle, sulfate-free shampoo. Harsh cleansers undo the good work of any mask or spa.
