Smells great

The shampoo smells great but I have really long hair and I'm not a fan of the feeling of my hair after I've washed this out.

Number 4 Shampoo

Great feeling Shampoo. Cleaned hair without drying out too much. Would definitely use this shampoo again but the price is quite high for me. Excited to pair this with the conditioner as well.

This shampoo was very good. I enjoyed the smell and lather it produced. I could notice the volume increase from my daily shampoo.

Love the way this makes my hair feel after using it - the smell is great, too! The pump makes for easy use in the shower and a little goes a long way.
