spray pump broke
The actual product is wonderful. It gives my hair more body and “thickness”. My issue is with the pump. I’ve only used about 25% of the bottle and the spray pump has already malfunctioned. Now I have to pour it out in my hand and try to work it into my hair. For the price of this product, I expect better.
