Our top pick for the best overall hair growth conditioner is the Redken Extreme Length Conditioner. This formula is enriched with amino acids, citric acid, and arginine, which blend together to ward off all types of damage — including more extreme situations — while also providing an ideal environment for hair growth.

What Is Deep Conditioning? Deep conditioning is when you apply good, thick hair conditioner or mask to your freshly washed hair. You can leave it in for anywhere from 15 minutes to an hour, whatever suits you best. I like to leave deep conditioner in for a while, usually an hour.

Depending on the condition of your hair, you should use a deep conditioning treatment around once a week. However, if your hair feels dry and stressed, you can use them up to 2-3 times a week.

Homemade deep conditioner Mix equal parts honey and olive oil. Leave on your hair for 20 to 40 minutes. Combine one egg yolk with two tablespoons of melted coconut oil. Leave on your hair for 15 to 20 minutes.
