    I used this for the first time and left it on for the recommended 20 minutes including application time. Did not result in pin straight hair but the frizz is goneeeee. And my hair is sooo easily manageable now. Strongly recommend!

    Shiseido hair straightening

    Posted by Leanna on 12th Jul 2021

    Did the hair straightening myself and was pretty easy to do. I followed the instructions on the bags and YouTube videos. The straightening cream and neutralizer worked really well for me and I have used about half of them. For reference, I have long, thick, wavy hair. Since these are hair chemicals, it would obviously have that chemical smell, most especially the H1 straightener, so make sure that you are working in a well-ventilated area - I was in the washroom, kept the door open, and the vent was on the whole time. The #2 neutralizing cream had a hot oil/conditioner scent so it was easier to deal with. It had been a week since I have used it and so far so good! I had been washing my hair daily (after the recommended 3 days no wash after treatment) and my hair looks healthy and straight. Expecting for these results to last for at least 4-6 months, based on previous rebonding experience but with different straightening cream. As for the seller, hair square, I had no problems whatsoever. This was my first time purchasing from them and I'm glad I did. I ordered June 21st with the basic/regular shipping speed to Calgary, got a shipping confirmation on June 23rd, and received the package via CanadaPost on June 30th. I have no complaints at all and would definitely order from them again if I need other products and once I finish the other half of the creams. Overall great product, legit seller, and good shipping!

    Order Experience

    Posted by V on 26th Jul 2020

    Ordered during COVID-19 for the very first time from this store since the stores/salons I usually shop from are closed. Owners were very accommodating. I would order again.

    Fantastic Product

    Posted by Unknown on 5th Oct 2014

    I love this product. I got this product about 8 months ago and I wanted to see how my hair would hold up after a second touch up and so far I have to say this product is amazing. I have very coarse African textured hair and it works like a wonder. I stopped using relaxers about 5 years ago and wanted to have my hair permanently straight. I did a lot of research and came by Japanese Hair straightening and I have to say it is one of the best decisions I have made for my hair in a long time. I love it and I'm happy I found an alternative to relaxers.
