I recently visited Centro Bellezza, a salon and beauty center located on the first floor of Moodi Tower in Salmiya, and tried their Keratin and hair dyeing.
If you want to do Keratin and hair dyeing, it's preferable to do Keratin first and then dye the hair after a week and that is based on the advice they gave me.
As for the Keratin, they wash the hair at first, apply the Keratin product that has a very strong odor and then heat the hair for 20 minutes.
After that, they keep the hair for some extra time, blow dry it and straighten it at the end without washing.
Then you have to come back the second day to straighten the hair again and on the third day as well to straighten the hair and wash it and then blow dry.
The results of the Keratin and the hair dyeing were so good and all in all, I was impressed with their good service and friendly staff.
As for the prices, the Keratin cost 70 KD and that was an offer that they gave to the clients who downloaded their smart phone app by then.
The hair dyeing with blow dry cost 55 KD but note that the prices vary based on the length and the volume of you hair and this goes for the Keratin too.
And to get better results with the keratin, I bought the Keratherapy shampoo, conditioner and mask. The shampoo is 8 KD, the conditioner 8 KD and the mask is 10 KD.
Note that the mask should be applied once a week for 20 minutes only.
