Great long term results
I saw results after few weeks. My hair growth is very quick by nature, but I noticed way more growth than the usual since I started to use this shampoo

All time favourite shampoo.
I used to use all soft now I use this. They’re both amazing for low-medium porosity wavy hair. This smells like marshmallows in a really expensive & luxurious way. It lathers like crazy without stripping my hair. It feels like having my hair washed at the salon. Pretty sure shampoo can’t make your hair grow faster but this keeps my hair long and healthy. Repurchasing this forever.
