One of the most popular products in the male grooming market is beard oil.
This will always require a carrier oil - and by that we mean a base oil that can be used as the bulk of your product that carries and dilutes the stronger oils such as essential oils or fragrance oils that you may use.
They can range from the inexpensive Sweet Almond Oil to the more luxurious oils such as Golden Jojoba Oil or Argan Oil (the one known as the liquid gold!). Or you can use a mixture of several different oils.
Coconut Oil is often used but this will come as a solid block so try using the Fractionated Coconut Oil which is in a liquid form.
