My favourite all time non edible deep conditioner has got to be Natural Classic Henna Treatment Wax. Words cannot describe the love I have for this product! Like it says it will not colour your hair trust me I have been using it for years now can’t remember exactly when I started using it but it has been a staple ever since. It’s easy to apply spreads well and perfect for detangling. Not only does it condition but it leaves my hair very soft. If I was to rate it I would give it an 11/10 it’s that good I absolutely love it and would recommend it any day. Can be purchased at beauty supply stores and online.
