Hemp seed oil has emerged as a popular ingredient in many beauty and health products, particularly for its potential benefits for hair. If you’re new to this world and wondering whether hemp seed oil can actually help with hair growth, let’s break it down step by step.

Before we delve into hemp seed oil, let’s understand our hair better. Our hair isn’t just a fashion statement; it’s a complex part of our body that needs care and understanding.

  • What is Hair? Hair is a filamentous biomaterial, primarily made up of the protein keratin. It grows from follicles found in the dermis, or skin layer.
  • Hair Follicles: Think of these as tiny factories in your skin responsible for producing hair. Healthy follicles mean healthier hair production.

What is Hemp Seed Oil?

Hemp seed oil is a nutritious oil, rich in fatty acids and other essential compounds, that’s extracted from the seeds of the hemp plant (Cannabis sativa). Don’t be confused; even though hemp is a variety of the Cannabis sativa plant, it contains negligible levels of THC, the psychoactive component found in marijuana.

Does Hemp Seed Oil Promote Hair Growth?

Yes, hemp seed oil, has properties that may promote hair health and potentially aid in hair growth. However, more specific research is needed to confirm its direct impact on hair growth.

Hemp Seed Oil’s Nutritional Profile:

Hemp seed oil’s potential benefits for hair growth can be attributed to its nutritional profile. The oil contains:

  • Omega-3 and Omega-6 fatty acids: These polyunsaturated fats have anti-inflammatory properties and are known to stimulate hair growth.

  • Gamma-linolenic acid: This fatty acid is known to stimulate the growth of keratin, a major component of hair.

  • Vitamins and minerals: Hemp seed oil is rich in vitamins D and E and minerals such as calcium and magnesium, which contribute to healthy hair.

How Does It Work?

There are several ways hemp seed oil can promote hair growth:

  1. Nourishment: The Omega fatty acids in hemp seed oil penetrate the hair shaft and provide nourishment, which is essential for strong, healthy hair.

  2. Scalp health: A healthy scalp is the foundation for healthy hair growth. Hemp seed oil’s anti-inflammatory properties help in treating scalp conditions like dandruff, which can inhibit hair growth.

  3. Increased blood circulation: The massage of hemp seed oil onto the scalp can increase blood circulation, which in turn stimulates hair growth.

How to Use Hemp Seed Oil for Hair Growth

1. Direct Application

This method involves massaging warm hemp seed oil directly onto your scalp. This can stimulate blood flow, which may encourage hair growth.


  1. Take a few drops of hemp seed oil and warm it slightly.

  2. Apply it directly to your scalp.

  3. Massage it in for about 5-10 minutes.

  4. Let it sit for 30 minutes to an hour before rinsing it off.

The scalp massage can help stimulate blood flow to your hair follicles, promoting hair growth. A study published in the Journal of Physical Therapy Science found that scalp massage can increase hair thickness.

2. In Your Products

Adding hemp seed oil to your shampoo, conditioner, or hair mask can infuse these products with the benefits of hemp seed oil, including the fatty acids that may promote hair health and growth.


  1. Take your regular shampoo, conditioner, or hair mask.

  2. Add a few drops of hemp seed oil.

  3. Use these products as you normally would.

By incorporating hemp seed oil into your hair care routine, you can provide your hair with essential nutrients every time you wash or condition your hair. The fatty acids in the oil may help improve hair texture and prevent dryness.

3. DIY Hair Mask

A DIY hair mask with hemp seed oil can offer a deeper conditioning treatment for your hair.


  1. Mix 2 tablespoons of hemp seed oil with 2 tablespoons of coconut oil and 2 tablespoons of aloe vera gel.

  2. Apply the mask generously to your hair and scalp.

  3. Cover your hair with a shower cap and let the mask sit for about 30 minutes.

  4. Rinse thoroughly.

Hemp seed oil, coconut oil, and aloe vera all have properties that can benefit hair health. Coconut oil has been shown to reduce protein loss in hair, and aloe vera has moisturizing properties. Combined with hemp seed oil, this mask can provide a nourishing treatment for your hair.

Tips for Buying Quality Hemp Seed Oil

If you’re convinced about trying hemp seed oil, here are some shopping tips:

  1. Check the Source: Ensure the oil is extracted from organic hemp plants.

  2. Cold-pressed: This method retains most of the nutrients.

  3. Transparency: Brands should provide information about third-party testing for purity and quality.

Is There Any Scientific Proof?

When we ask for “scientific proof,” we’re essentially looking for studies or research that show hemp seed oil can benefit hair growth. The truth is, while hemp seed oil is celebrated in the wellness community, research specifically on its hair benefits is still budding.

  • What We Know: Fatty acids, like omega-3 and omega-6, which are abundant in hemp seed oil, have been linked to hair health. For instance, a study in the Journal of Dermatological Treatment showcased that participants who took omega-3 and omega-6 supplements saw a decrease in hair loss.

  • The Bigger Picture: While this doesn’t directly prove hemp seed oil’s hair growth prowess, it does hint towards the benefits of the nutrients present in the oil. So, it’s a promising lead, but more in-depth research is required.

  • Sample Story: Think of Lisa, a blogger who swears by hemp seed oil. She’s been using it for months and has noticed her hair looking healthier and shinier. While Lisa’s experience is real and positive, it’s an individual experience, and scientific studies would look to see if these results are consistent among a larger group.

Can Everyone Use It?

The great news is that hemp seed oil is like that friendly neighbor: generally kind to everyone. But, just like with any new product, caution is advised.

  • Patch Test First: If you’re new to hemp seed oil, dab a little on the inside of your wrist or behind your ear. Wait for 24 hours. If there’s no redness or irritation, it’s a green signal for you.

  • Allergies and Sensitivities: Some people might be allergic or sensitive to components in the oil. In these rare cases, using the oil might cause irritation or breakouts.

  • When in Doubt, Ask: If you’re unsure, or if you have a skin condition, it’s always smart to consult with a dermatologist or healthcare provider.

While the benefits of hemp seed oil for hair are evident from anecdotal evidence, it’s crucial to consult with a dermatologist or hair care expert before making significant changes to your routine. Everyone’s hair is unique, and what works for one person might not work for another.

Nevertheless, given the numerous potential benefits, hemp seed oil is undoubtedly worth considering for those looking to enhance the health and appearance of their hair.


 Which oil is best for hair growth?

Different oils offer varied benefits for hair growth. Popular oils include castor oil, coconut oil, jojoba oil, rosemary oil, and hemp seed oil. Each oil has its unique properties; for instance, castor oil promotes circulation while hemp seed oil nourishes with omega fatty acids. The “best” oil often depends on individual needs and hair types.

Can you leave hemp seed oil in your hair overnight?

Yes, you can leave hemp seed oil in your hair overnight. Applying it as an overnight treatment can allow for deeper penetration into the hair and scalp, maximizing its nourishing benefits. However, always do a patch test first to ensure no allergic reactions.

Does hemp seed oil thicken hair?

There’s anecdotal evidence suggesting that hemp seed oil can help thicken hair and reduce hair loss by promoting a healthier scalp environment. The omega fatty acids in the oil might strengthen existing hair strands, but direct scientific evidence linking hemp seed oil to thicker hair is limited.

Can you put hemp oil on wet hair?

Yes, applying hemp seed oil to damp or wet hair can help lock in moisture. Just like any other oil, it acts as a sealant and can help retain the moisture content of your hair, making it feel soft and more manageable.

Can I take hemp seed oil every day?

Hemp seed oil is generally safe for daily consumption when taken as a dietary supplement. It’s rich in essential fatty acids and nutrients. However, as with any supplement, it’s important to follow recommended dosages and consult with a healthcare provider, especially if you have any existing health concerns.
