Greetings. We’re here with a tutorial on hair rebounding from Rokhsare Pasebani Academy.

Before we begin, we have to know about the hair a little bit. We have to know how curly the hair is. We choose our product based on the percentage of curliness we want to straighten. Before any type of chemical work on hair, we have to wash it first with a suitable shampoo and after drying, we can start our Rebounding or Japanese hair straightening. Rebounding is a very delicate and smooth straightening method.

How can we perform this process without facing issues?.

If our hair is thin and has undergone bleaching or dye multiple times, we have to start with a powerful vitamin supplement. After applying the vitamin supplement to the hair, rinse and dry the hair and start the process after dividing the hair.

The amount of product you have to use must be calculated carefully, in a way in which you have no excess product left after the process. After dividing the hair into nine or eighteen batches, add the product to the hair, starting from the back and one centimeter away from the roots. After adding the product one centimeter from the root, massage the hair using two fingers towards the stem. After adding the product to each batch, leave it and move on to the next layer. The layer you are working on should have no contact with the previous layers at all, so when you work with one layer the one under it should be brushed or massaged. Both massage and brushing should be applied to the current batch at all times.

Let’s start with a small batch. Keep in mind that this is an extension since there is usually no curly hair used on model heads. We’ve added the product one centimeter from the root and now are massaging the hair between the two fingers. Here you can push the product half a centimeters toward the root. The remaining half centimeter will be soaked as a consequence of this. Pick another batch and add the product. Massage the hair toward the stem. Also, massage the hair the half-centimeter towards the root. Do the same to all the other layers. We’ve added the product to the hair, brushed and massaged the hair toward the stem and massaged a little toward the root. We continue until the end and then cover the hair superficially. No heat should be applied here. Just let the hair sit under the cover for twenty minutes.

Remove the cover after twenty minutes and pick three strands of hair to test. You can test the result by using the hair to form a knot. If the knot opens after twenty minutes, it means the product has not affected all the sulfur bonds yet. If the knot didn’t open, which is usually true for thin and European style hairs, it means the process is done and you can prepare for a rinse. If the knot opens, we have to give the hair ten more minutes. Here I’m doing a knot test. Let’s tighten the knot and see if it will open. This knot opened and we have to give the hair ten more minutes. Give the hair thirty to thirty-five minutes and 45 minutes max for thick hair overall.

After passing the required time, we have checked the hair again and realized it is ready. We have rinsed and removed the extra water, and now we can blow dry the hair using medium heat. After blowdrying, when the hair is completely dry, prepare the hair and divide it for hair ironing. Our ironing process should be completely professional and principled. The heat should be specified based on how thick or thin the hair type is and if it’s bleached or dyed. This hair was a healthy one and was only dyed, but for bleached hair, we can’t use this method of rebounding. There are other straightening techniques we can use.

Our hair is healthy and we have prepared for ironing. Usually, it takes two to three hours to iron the whole hair. Rebounding usually takes six to seven hours and we have to tell the client how long the process will take to prepare them for the long process.

To iron the hair we need to use a two-sided brush. This will make the work better and easier for us. It’s important not to let strands of hair left outside the iron. The heat should be 230 degrees for healthy hair and for dyed or thin hair 210 to 220 degrees is advised.

When we mean by professional ironing is the movement of the iron on the hair shouldn’t be too fast, like this, or too slow. After adding the straightening cream, we have relaxed the sulfur bonds and put them in correct formation by ironing. We have to pass through each batch at least seven and at most ten times. Start ironing the next batch. The brush we use makes the process much easier. No strand is left outside the hair and we’ll have a satisfying result.

After ironing the whole hair in a professional manner, and made sure the result is proper, we have to leave the hair for a while. When we’re done with the front of the hair, which is the last part we work on, start your timer for fifteen minutes until the hair is completely cool. This will help the sulfur bonds cool down. Next, divide the hair and use plastic clippers. Your product should also be held inside a plastic cup or bowl. Under no circumstances should you use metallic material.

Separate thin layers starting in the back of the hair to add the neutralizing material. This is the stage where the neutralizer is added to the hair. The process is the same as before. Add the product to thin layers and massage the hair toward the stem and half a centimeter toward the root. Do the same for the next layer. Overall, there should be no excess material on the hair during either of these procedures. The excess material could damage the hair. The neutralizer should always stay on the hair five minutes less than the straightening material was. If the straightening material was on the hair for forty minutes, the neutralizer should stay on for thirty-five. After our calculated waiting period, we have to rinse the hair and use a rich hair mask. After giving the mask ten minutes, you can wash the hair with a shampoo and a suitable conditioner. The hair should definitely be covered completely with a good conditioner or mask.

In the end, you’ll have a healthy, bright and straight with a long lasting lifetime. This is what a good rebounding looks like. If you see a wave in the hair after the process, then the rebounding was a failure. In a permanent rebounding, there’s no need for multiple ironing, until you cut the hair or the root grows too long. You have to repeat the process to cover the hair growth every six months. If you add the product to the parts that have already gone through this process, then you can damage the hair.

This is a two-step rebounding. We talk about three phase and single phase rebounding in our classes. As well as, omega therapy and emballage.
