Kryolan GF-QAT 30 (Stronger than GF-Qat N)
Also known as GAFQAT, this is a classic professional product designed to be an extreme hair flattener that is ideal to use on hair before applying bald caps. It has incredible hold that unlike hair gel or wax does not spring back up after time, making for ideal bald cap application.
Also good for using to shape the hair. It dries hard and will wash out with shampoo.
