I always snatch up samples like this when they’re available. Why? Because Shampoo/Conditioner is expensive & it never fails that when I buy a new brand my hair gets dried out immediately. I’d much rather try a sample & find out I don’t like it then buy 2 whole bottles of products. They always end up under my sink for ages.
You know what else these samples are good for? Taking to the hospital when you have a baby! Most may provide you with shampoo if you ask, but usually not conditioner.
Samples arrive in 8-12 weeks.
