What is the best hair product out there?

Can you recommend a hair product must-have or a few of them?What is the best hair product out there?
Coconut oil. It's available at health food stores and some regular grocery stores. Around $12 a jar. Use it as a hot oil treatment one time weekly for soft, shiny, manageable hair. Heat up a small amount (or more if you have longer hair) in the microwave. Not too hot or you could burn yourself. Usually 20-30 seconds will do the trick. Put it on dry hair. Cover your hair with a shower cap and/or towel. If your hair is very damaged, leave it on overnight. If it's in decent condition, leave it on for 30 minutes or up to 3 hours. Then just wash and condition as usual. It comes out easily. You'll notice results the first time you use it. But it gets even better it you continue to do over a period of time.What is the best hair product out there?
