Castor Oil + Biotin Shampoo Bar - HAIR GROWTH

Have just started using it so can’t review how it works as far as thinning hair, but lathers up great!

I thought it was rice protein bar. It also smells like motor oil and peppermint. I got the castor oil and biotin shampoo and conditioner bars.

Bar lathers well but I do not care for the smell. It cleaned my hair without problem and rinsed out well.
