Best there is. It's like pouring lotion on your scalp. Leave it in for 2 to 5 minutes. Go to a salon and pick some up in bulk 1/2 to 1 liter for $10 to $25. It's way over priced at grocery stores. I use 4 times a week and it has done wonders.
Not sure if you're using conditioner but if your not, you should start. I also find that using "better" shampoos and conditioners has worked for me. ALways condition after using nizoral too.
