Excellent hair oil!

My hair has never been more healthy and less frizzy! I apply Biosilk both on wet, clean hair, and to my dry hair before and after styling. The oil seal protects my hair from heat damage. The smell is absolutely amazing! Worth the purchase price alone! But with my coarse, medium curly hair the benefits are just as great as the smell. I highly recommend this product. A 34 ounce bottle usually lasts over a year, sometimes eighteen months depending on the length of my hair. Right now my hair is to my shoulder blades. It's always touchable soft and perfectly shiny, without appearing oily. I've been told it can be used on the skin as well, but I find I need face lotion as well. I am so glad I found this product!!

What a difference it makes on my hair!

I truly love, love, love this product! I have wavy/curly hair and I've tried many, many, products over the years to try to get my curl more defined. Nothing worked until I tried Biosilk Silk Therapy. What a difference! I shampoo my hair with my favorite hair shampoo, rinse, and towel dry. I use Biosilk Silk Therapy as my leave-in conditioner and let my hair air dry. Sometimes I don't even have to use any additional products and my hair has nice beach look waves. My hair looks healthy and glossy. If I add a cream gel, my hair gets really curly. I love Biosilk! I also use it on my skin, especially after I have shaved my legs. The fragrance is really nice too. I highly recommend this product!

Great bargain!!

I've been using Biosilk Silk Therapy for years now and have suffered the cost of the bottles until a year and a half ago when I discovered the tri pack of conditioner, shampoo and the Silk Therapy. I was paying $29 and that was a better price for the 12oz bottle than just buying the single Silk Therapy alone. This seems like it is a lot of money but mathmatically you will save A LOT by buy it this way.I wash my hair everyday and have perms put into too because I'm not fortunate enough to have naturally curly hair. The stylists are always amazed at how great my hair is, no split ends, no dry shafts. When they find out that I use this they don't even bother trying to sell me their salon products because obviously it works and works well. I don't even use conditioner on a regular basis, just a quarter size, or larger as my hair gets longer, of Silk Therapy and it does the trick and makes my hair smell super on top of it!I can't say enough good things about it. I've tried other products when I didn't want to fork over the cost of it and have always felt sorry and went back to it. Wasting money on other similar products because they do not work as well.I didn't use it to soften up my skin much because of how expensive I felt the other bottles were but now I don't mind and it really helps soften up the hard soles of the feet and the back of the elbow.I hope they don't discontinue this size!
