Key Features:
Note: At LovelySkin, we take your health and the health of your hair seriously. We have contacted OLAPLEX and spoken with their scientists about the recently announced issues. From statements by their scientists and CEO, it appears that there is no reason to believe that OLAPLEX products cause hair loss or hair breakage. Every OLAPLEX product is thoroughly tested by both their in-house formulators, as well as independent third-party laboratories. They use industry-standard Human Repeat Insult Patch Tests, also known as HRIPT, in which every OLAPLEX product is tested on humans to ensure it doesn’t cause skin irritation, inflammation or sensitivity. When hair products pass these industry-standard tests, it also means there is no caused inflammation to the hair follicle, which is a known cause of hair loss. If you are interested, you can read these findings on the OLAPLEX website.

This is my second favorite leave in/styling product only second to no. 10. It is a decent curl gel and nice when I straighten. It leaves my hair shine and cuts the frizz. Sometimes I combine it with no. 6 or 5L if I need more moisure.

I am very happy with the results of this hair serum. It’s a great heat protectant and also really softens my hair when air drying. Great product.

This serum has replaced the serum (also amazing) that I was using. This serum helps remove tangles before I brush my hair, and smoothes my wet curls before I use my Olaplex Leave-in Conditioner (with a drop of Olaplex Oil). What a hair regimen!

Previous to discovering Olaplex #9, I used #6. I like #9 even more! It's not heavy; a little goes a long way - and it protects against the heat.

I have curly hair that can get frizzy. Just a small amount on damp hair keeps my hair in check. You don’t need much and it feels great!

I like using this serum, and would repurchase. I like all the Olaplex products I have tried, but this is the easiest to use. Just put onto hair and it absorbs nicely, and does not leave my very dry hair oily or sticky or crunchy. It is a nice scent like all the olaplex. It is not like a hair oil, and not like a thick conditioning balm type product. It is light and slightly nourishing.

I use this hair serum after shampoo/ conditioner. This makes hair smooth. free from tangles. Also nice to apply on dry hair to give an extra moisture look.It doesn’t weigh down the hair and makes it manageable. As part of hair treatment regimen makes hair healthier and fuller.

This Olaplex is my new go-to styling product. It makes my hair smooth but not limp, and it doesn't have an oppressive scent.

I originally received this as a free gift with purchase. I have fine, thin hair and once I tried this I knew I would be purchasing it again. I use it after I towel dry my hair and it makes my hair feel stronger and more resilient to heat from the hair dryer and curling iron, which I only use occasionally.. This serum seems to strengthen my hair as well. I am very happy with this product and will continue to buy.

My shoulder length hair is baby-fine but a bit thin and tends to be fly-away in the winter. Working No. 9 into the ends, or mixing it with No. 6 and massaging it from root to ends, after washing helps smooth it out :-) It won't make your hair greasy unless you get heavy-handed. I'll definitely be keeping this in stock!

Olaplex #9 says its a nourishing hair serum and heat protectant. It leaves hair smooth when applied to damp hair and let air dry. I add 2 drops of the bonding oil to #9 and apply.
