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.
