            From the moment I put this on my hair, my split ends instantly felt less rough and the appearance of them disappeared. As someone with very naturally fine and weak hair that is very prone to split ends, it's wonderful to finally have a product that temporarily seals them. Of course it's not going to fix them forever, but it is a great temporary alternative to cutting your hair.

                          I have bleached blonde hair and it loves splitting. Using this in combination with the anti-breakage spray, I've noticed a huge difference in the couple of weeks following my last salon visit. It also smells really good and my hair still smells great even after my daily sweat session.

                              There are many ways to use Redken Extreme products. Please feel free to consult your stylist for a personalized haircare regimen.

                              You have asked for the best way to use the Extreme Length Sealer and Primer, so here it is: After using Redken Extreme Shampoo, apply Extreme Length Primer on damp hair from root to ends. Leave on 2-5 minutes. Rinse. For best results, follow with Extreme Length Sealer. Consider following up with Extreme Anti-Snap for added protection from breakage and damage.

                              When using heat tools, Pillow Proof Blow Dry Express Treatment Primer protects hair from up to 450 degrees. It also strengthens, hydrates and nourishes the hair. Check it out at Ulta by following this link: http://tinyurl.com/lkto7tt

                              This product can be used with a primer, but it isn't necessary. Redken Extreme Length Sealer is meant to be applied to damp or dry hair. It should be brushed onto the ends of your hair. Then go ahead and style as usual.

                              Redken Extreme Length Sealer is a great product for split ends and distressed/damaged hair. For deeper conditioning/moisturizing, consider using Strength Builder Plus fortifying mask, which does need to be rinsed out. Then apply Extreme Length Sealer when the hair is towel dried.

                          • Q:

                            My hair is kinky and frizzy, and I keep it chemically relaxed. Frizz Dismiss works very well for the frizz. However, I would like to grow my hair, so I'd like to try Extreme Length. Can I alternate the two systems? For example, use Frizz Dismiss one shampoo and Extreme Length the next? Or, can I use the products together? For example, I would use the Extreme Length shampoo and mask, then add the additional Frizz Dismiss conditioner.

                            Thanks for your assistance.

                              These products have been formulated to work together for maximum benefits. If you use one or the other, you will receive the benefits of that one product.
