This means a salon-quality shampoo made with high-quality active ingredients. Spend some time looking at the list of ingredients and choose one based on the contents, not just the name brand.  Avoid ingredients like sulfates (ammonium lauryl sulfate, ammonium laureth sulfate, and sodium lauryl sulfate), isopropyl alcohol, formaldehyde, and propylene glycol. These ingredients will dry out your hair, break down healthy hair proteins, and leave your hair prone to more damage in the future.  Look for ingredients like sodium cocoyl isethionate, sodium lauroyl methyl isethionate, and disodium laureth sulfosuccinate. These compounds are gentler than the sulfates used in many cheaper shampoos and are derived from more natural ingredients like coconut oil.  You can also choose shampoos that contain glycerin and panthenol. Glycerin helps fortify your hair by creating a protective barrier and panthenol allows your hair to retain more moisture and thickens the hair follicles. This kind of shampoo will help fortify your hair by creating a barrier between the hair and any heat you may apply to your hair (through blow drying, straightening, etc.). Leave it in your hair for five minutes and then rinse it out. Alternate between using this shampoo and your other high-quality shampoo. Don't use both during the same shower. Over-washing your hair can leave it drier and damaged in the long run. You want to make sure you allow your hair to fully absorb the products in each of these steps. Towel drying your hair will help it soak up the benefits of the shampoo treatments before moving on to the conditioning steps. These kinds of conditioners will work to restore the hydrolipidic barrier and prevent future dehydration in your hair. Normally, these are not leave-in conditioners. You will typically apply the conditioner to your hair while it's wet, massage the conditioner into your scalp, and then rinse it out.
