My hair is extremely coarse and porous, and I haven't been able to find something that works well for keeping my hair moisturized without being too heavy. Apparently my hair is just right for the Mixed Silk products, because all of it works perfectly! It's really soft and glossy now and much more manageable, I can skip serum every once in a while without it looking like a total nightmare. If you have the same hair type, I would recommend giving it a try. Very much worth it for the price - $15.00 plus tax for everything on the $5.00 sale.
