Directions
leave-in molecular repair hair mask:
In the shower:
- Shampoo, don‘t condition.
Out of the shower:
- Using a towel, gently dry hair until damp.
- Begin with 3 pumps of K18 mask.
- Only add more as needed, up to 9 pumps. Average use is 6 pumps (this is a highly concentrated formula, so you‘ll need much less than traditional masks.)
- Apply evenly from ends to roots.
- Let sit for four minutes.
- Don‘t rinse out.
- Style as usual after the four minutes is up (fine to add heat protectant or styling product now).
- Use for the first four to six washes, then swap to maintenance mode and use as needed.
AstroLift™ reparative volume spray:
- Shake well.
- Hold bottle 4-6 inches from roots + hair.
- Spray generously throughout.
- Blow dry for added volume.
Can be applied to dry or clean, towel-dried hair, with or without heat styling. Buildable, lightweight spray can be used in between washes to amplify volume.
PRO tip: To maximise benefits from the reparative K18PEPTIDE™, apply on clean, towel-dried hair and wait 4 minutes.

A let down
So disappointed, the repair treatment makes my hair greasy and I purposely try not to use too much. I've heard you can use it as normal and wait 4 minutes then rinse and condition. Think I'll have to try it that way.
The spray smells lovely but truly don't think it does anything for me

Silky soft but zero volume
Super soft but zero volume. I have very fine hair and whilst both products made my hair silky soft, my hair was flatter than when I use no products at all. I used them on different days too to see if that made a difference but no still zero volume, shame. It would have been 5 stars for silky softness though.

Mask is good, spray doesn't give me volume
I like the mask, leaves my hair really nice. It's expensive but if you can splurge I would buy it. The volume spray unfortunately does nothing for me. Considering you get it for free I guess it's alright but it's literally just not being used at all. Tried just spraying and air-drying. Tried blow-drying. Doesn't add any volume.
