Hi friends!!

Ever since I was a kid, I was cursed with really oily hair. I really hated it because my scalp would itch, or you could literally see the oil streaks on my hair. What made this worse was that I loved to colour and perm my hair, and it probably contributed to more damage.

So recently, I visited this Japanese hair salon at Orchard called Devonshire Hair Studio. I was there to try out their hair spa treatment using this product called by one sii. The hair studio was about a 10-minute walk from Orchard MRT. At first glance, I really liked how the salon looked chic and minimalist - almost like a cafe! Almost every inch of the place made a nice photo background, especially the stairs leading up to the second floor.

The hairstylist sat me down and explained to me what the spa benefits were, as well as a short introduction about the by one sii Smooth Repair Essence that we would be using. So apparently, doing stuff to your hair such as colouring or perming can result in a significant build-up of reactive oxygen species (ROS)" and "residual alkali" on the hair, and this can cause ageing or even cancer and arteriosclerosis. But of course, this doesn't mean that dyeing your hair is the only cause for ROS - ROS is also caused by other factors such as UV rays, high stress and even pollution.

So yes, don't cancel your hair appointment just yet!

The good news is - antioxidants are said to remove ROS, and this is where by one sii comes in because the Smooth Repair Essence is blended with louseki stone which has high antioxidant power! It is designed to tackle thin, brittle hair, as well as reduce scalp smells. It also suppresses tangling and frizziness and is perfect for us living in Singapore since it prevents your hair from looking flat under the hot Singapore sun.

Besides the hair spa treatment, I also requested for a haircut! Here's how it looked before! As you can see my hair was really long and my scalp was rather oily and a little red.

The hairstylist cut my hair to the desired length and sent me to the shampoo station just to get my hair washed and cleaned before anything. Then she proceeded to start on the treatment using the by one sii Smooth Repair Essence.

To use, she mixed shampoo and the repair essence in a 2:1 ratio, and then applied the thick foam to my scalp. And since it was a spa, she also gave me a really good shoulder and head massage!

The foam was left in my hair for some time, and then it was time to wash off! After washing and drying, she proceeded to trim my hair and blow it dry. Once it was dry, I immediately could tell the difference - running my hands through my hair, the texture was the smoothest it's been in years. It was like silk! I was really surprised at the instant results.

From being tangled and dry like the Sahara Desert, it was now extremely glossy, as if I put some sort of shine over my hair (which there wasn't). Another really interesting thing was that my hair was smooth but not flat, and the hair strands literally rose from the root to produce volume.

Here is a comparison of the redness of my scalp before and after!

The final stage was to style my hair, and I requested for some simple curls. I absolutely love how it turned out!

by one sii Smooth Repair Essence for home use


I got to bring back a bottle of the by one sii Smooth Repair Essence to use at home, and have been using it every day for about one week. I usually dislike using hair treatments because some of them can be inconvenient to use or you need to leave it on your hair for long period of time, but the repair essence is really easy to use. Like mentioned above, just mix the shampoo and repair essence in a 2:1 ratio on your palm and apply it on your hair. You can leave it on after a while, but I usually take my time to really massage my scalp and then rinse everything off right after.

I seriously love the treatment because my hair now is much bouncier and less oily, especially at the roots. I really hate how I look with flat hair, so being able to prevent that now just makes me happier with how I look.

If you want to try the product out and experience the changes for yourself, feel free to get yourself a bottle of the by one sii Smooth Repair Essence from their online store. On the other hand, if you're looking for a nice hair pampering, drop by the Devonshire Hair Studio to experience their hair spa treatment starting from S$30!
