Great product
Best product for dry or damaged hair. Leave your hair looking silky, soft, and looking well hydrated. Too much product will cause your hair to look oily. I ordered a large bottle that will last for about a year.

Needed in a dry climate with strong UV exposures. GOOD dupe for Olaplex no9
If your hair has been untamed and you live in a more dry and UV exposed climate, this product can help your hair behave how you'd expect it would in a less dry climate. Without the use of heat/gel/hot blowdrying tools. It can also provide relief from clarifying shampoos which affect your hair when you are in a more dry climate. Compared to Olaplex antioxidant serum no9, it is an ok dupe great for the value. It lasts longer than no9 if you have lots of hair. Less product is required than no9 for distribution. Though it makes no claims to protect hair from UV/free radicals like no9 it will help you get your hair healthier and where you want it in 3 months if you're trimming off your split ends periodically. It will weigh down more your hair than no9 and make your hair appear more fatty after the first day. Not a bad thing if you live in a arid-climate that dries out your hair. Certainly better than applying no protections or using a plant-oil for your hair inbetween washes. Unlike Olaplex no9 serum, the application lasts days, if you apply to damp hair after washing. It also has a higher viscosity that requires less amount and less applications post wash. It can save you between wash days. If you are not trying to dazzle with your hair down hairstyle on the daily and are ok with heavier/fattier appearing between washes. For example in a dry climate you might wear a protective style and a sun hat. It works very well for growing hair. The product has enabled me to grow out healthier hair, seal hair ends, and brush my hair with ease all week long. Where my hair was previously prone to daily tangling, split ends and dryness. A great product with great value. A small provision also last a while and the proce os ve ty reasonable. This product has been life changing for my hair. It is common for shampoos and washes to dry out hair, despite product claims to add moisture or body. In an arid climate, that simply doesn't apply. This product will leave hair manageable and helathier if used as directed (apply to damp hair after washing. Reapply as needed to dry hair to untangle and reduce frizz).

Great quality, smells nice, and makes my hair very touchable!
My mother turned me onto this stuff years ago and I still love it. You need a very very small amount so a bottle lasts quite a while. After washing and towel dry, I massage this into my wavy hair and it feels silky smooth and soft until I wash it again. It also smells really nice (but not strong or too much like perfume). If you have dry hair or split ends, you need to try this magical potion!

Softens type 4 hair
Softens type 4 hair. I brought this product because it had great reviews (over 40k). I was looking for a product that would soften my type 4 hair. This is literally the best product I have ever used.

Makes Hair Silky and Smooth
This BioSilk Silk Therapy is amazing! It leaves my hair incredibly soft, shiny, and frizz-free without feeling heavy or greasy. A very small amount goes a long way, and the scent is lovely. My hair looks healthier and more manageable after using it. Definitely a must-have for anyone wanting smooth, silky hair!

What can't this serum do? I love it! I use about a 10 cent piece worth on wet hair after showering, working it through the ends and then running my hands with the leftover remmants of the serum through the rest of the hair. It makes my hair smell amazing, and leaves it soft and shiny. For a frizz-free finish I pop another tiny dab in my hands (about half a 5 cent piece), then rub my hands together and just work it over my whole head very lightly after I finish blow-drying... and voila'! Soft, shiny hair that smells divine. But wait, there's more! If you wash your hair at night and need to re-style in the morning, just pop a little into a spray bottle mixed with water and shake it up really well. You can use this to wet your hair down before re-styling, or just as a de-tangler. But, that's not all! Silk Therapy is also amazing for wigs and hair extensions (both human hair and synthetic). Price-wise it's not the cheapest product, but I think it's great value, you really don't need to use much, so it goes a long way.
