List of Beard Oil Ingredients Can Block DHT and Suppress Beard Growth

beard oil and other beard care products on a table

Beard oils are all the rage right now.

Just putting up the terms “beard oil” to Amazon, you will be delivered over one thousand different beard oil results, from hundreds of brands.

Most men only look at the scent or cool bottle when deciding what beard oil to buy, but this can be a huge mistake…

…As the most important factor in beard oils are the actual ingredients, and how they impact the health of your beard.

You see, facial hair is fueled by androgenic hormones; testosterone and DHT, and certain oils can suppress these hormones, resulting in suppressed beard growth rate.

So below, we have listed the worst offenders; the beard oil ingredients (carrier oils and essential oils) that are known to suppress testosterone or DHT, and possibly harmful for your facial hair growth.

Possibly Harmful Beard Oil Ingredients

  • Safflower Oil & Rice Bran Oil: Both contain high amounts of GLA (gamma-linoleic acid). This polyunsaturated omega-6 fatty acid is prone to lipid peroxidation and one of the strongest natural DHT blockers.
  •  Almond Oil and Sweet Almond Oil: Being quite high in polyunsaturated fat and omega-6 linoleic acid, sweet almond, and almond oils can suppress beard growth rate, by blocking DHT and lowering testosterone.
  • Sunflower Seed Oil & Sesame Oil: Both of these are very high in polyunsaturated fatty acids and in particular the harmful omega-6 linoleic acid, which is a known DHT blocker. Best if you don’t use these in your beard oils.
  • Peppermint Essential Oil: Commonly known as PEO the peppermint oil can possibly harm your beard growth rate through suppressing testosterone. These results were seen in several studies where peppermint and spearmint tea lowered androgens. It’s unknown whether this effect takes places when applied topically, but I wouldn’t risk it.
  • Hemp Oil: Rich in polyunsaturated fats, this oil is incredibly volatile and easily goes rancid on the face thanks to our good friend; lipid peroxidation. It can also contain some estrogenic compounds, such as ligands.
  • Amla Oil: This is an oil that comes from the Indian Gooseberry tree berries, and it has been shown in studies that Amla oil is bad for the beard largely due to the fact that the berries are one of the most potent 5-a enzyme blockers, and thus can suppress DHT.
  • Pumpkin seed oil: Although pumpkin seeds are high in zinc and some claim they’re great for testosterone production, most also fail to realize that the reason why pumpkin seeds can increase testosterone is through a mechanism of blocking DHT (leaving more testosterone as its the raw material for DHT production). For this reason, avoid pumpkin seed oil in beard products.
  • Tea Tree Oil: Last but not least, tea tree oil contains compounds that have been shown to be powerful antiandrogens; so powerful that they can grow man boobs to young boys. These same compounds are present in eucalyptus essential oil as well, which is why we don’t recommend it for beard growth.


Some beard oil carrier oils and essential oils are downright harmful to your facial hair growth and should be avoided.
