Perfect Me is a lightweight, milky-textured lotion product that claims to protect from heat damage, add smoothness, shine, and moisture to the hair. My hair is colored, fine textured but thick, somewhat dry, and sort of unruly. I've used this both with heat styling and air drying and it is a very nice product! It definitely does add some softness and shine to my hair without weighing it down or making it feel greasy. When my hair air dries it gets pretty wavy, and Perfect Me doesn't diminish that effect too much like other lotion-y leave-ins can do. It has a faint smell, but it fades away pretty quickly. One good-sized pump is enough to coat my shoulder-length hair, so I expect that the bottle will last for a fairly long time. I usually try to avoid spending very much on haircare products since I have found that many less expensive options work just as well for me, but I definitely think that this product is worth it. I can't say how it would work on coarser hair, but if you want something to smooth fine hair without adding too much weight, definitely give this a try!
