Aren’t there volumising hair shampoos on the shelves? Aren’t they supposed to add volume (thickness) to hair?

Castor Oil:

Castor oil has been used successfully for many years for increasing hair growth, not only for your head, but also for eyebrows and eyelashes. It is well known for the many health benefits it provides including its anti-inflammatory, antibacterial and anti-fungal properties. Castor oil is high in omega 3 fatty acids, ricinoleic acid, and vitamin E, in addition to many other minerals and proteins. These nutrients help nourish the hair and scalp to increase growth. Castor oil also increases circulation, which is critical for promoting hair growth.

How to use it: Take a few tablespoons of castor oil (use more or less depending on how long your hair is) and massage it into your scalp. Make sure to use pure castor oil that is hexane free, like this.

It is a thick oil so it may be a little difficult to spread. You can mix it with a thinner oil to make it a little easier to put on, like coconut oil. (Just mix 1/2 coconut oil with 1/2 castor oil). Continue to massage it into your scalp for several minutes, then begin to work it through the rest of your hair. Let it sit on your hair for an hour or two, then wash it out. Try to do this at least once a week or several times a week for better results.
