Oh! no no no no. Even though the principle is the same, they are different products, designed to do different things. X-tenso is an excellent product. Stick with it. Perming solution will never give you the softness, shine, and humidity resistance that X-tenso will. Plus it makes your hair more prone to breakage (perming solution that is). Wait until it is time to re-do your roots and just have your original stilyst do it. If you want to do it yourself (which I don't recommend) you can purchase the product on Ebay. There is a seller that carries it, and has complete instructions on how to apply it. Remember that the product should never touch the scalp (that is why is better to have it done by a professional). Follow directions carefully. Again I recommend just going back to the original stilyst and getting done. Your hair is your most important accesory. It is worth the expense.
