Review on Hair Bottox Expert Thermal Mask - Marine Collagen and Almond Oil - Formaldehyde-Free: Repairs Elasticity, Softens, Moisturizes, Adds Shine (8.8 oz) by Kristen Simon

This product contains formaldehyde which must not be used in hair botox. The eyes are irritated and you smell badly because of the presence of formalin or formaldehyde. This product has been banned in many countries because it causes cancer. I'm Brazilian and brought this thinking it was hair botox but it's not. My hair was falling out profusely every day because of this product and I also forgot to use a glove when applying, my hands were dry and burning after contact with this product. Straight and smooth are not worth buying with this dangerous product.
