CBD Oil For Hair: 5 Scientifically Proven Benefits 

CBD oil helps combat various hair-related problems: 

1. CBD Oil for Dry Hair 

Do you know what causes dry hair?

Each strand of hair is made of protein. A lack of protein can leave your hair looking dull and devoid of colour, making it dry. 

The good news?

A CBD oil supplement can be an effective remedy for dry hair.  

CBD contains amino acids and vitamin E, which contribute to silkier and shinier hair.

2. CBD Oil for Hair Growth

Look: Shedding some 50-100 hairs every day is normal.   

But if your thinning hair doesn’t grow back at the same rate it’s falling out, we have a problem.  

How does CBD oil help here?

CBD oil contains a few essential nutrients (including omega-6 fatty acids) that help maintain a healthy scalp. 

A 2021 study found people who applied CBD oil to their scalp for over six months saw successful regrowth patterns. 

Plus, applying CBD oil to your head helps seal moisture when sebum levels are low, promoting healthy hair growth.

3. CBD Oil for Hair Loss 

CBD oil helps grow hair. Great!

But can it prevent hair from falling out in the first place? 

Absolutely! CBD oil not only stimulates hair growth but can also slow down hair loss. 


Hair loss often occurs due to improper blood circulation to the hair follicle roots.

Research shows CBD oil can improve blood flow around the hair follicles when applied to the scalp. Increased blood flow means more nutrients are delivered to the hair follicle, reducing hair loss.

Interesting Fact: Did you know hair loss is caused by many factors like a lack of nutrients, genetics, and high stress levels? It happens regardless of your hair type!

4. CBD Oil for Damaged Hair and Breakage

Your hair is regularly exposed to dust, pollution, and harmful UV rays. 

The result? 

The hair follicles become lifeless and feeble — you may even get an itchy scalp. 

Don’t worry. 

Scientists have found CBD oil has potent moisturising properties that can help you achieve shinier and healthier hair. 

Pro Tip: General hair moisturising could help prevent your hair color from fading.

5. CBD Oil for Scalp Conditions

Dandruff, psoriasis, folliculitis, dermatitis, and eczema. 

What do they have in common?

All are pesky scalp conditions that occur when your scalp is irritated or inflamed. 

The good news?

CBD oil has strong anti-inflammatory properties that can nourish and soothe a flaky and itchy scalp. Its fatty acids can help moisturize your hair, as well as your scalp. 

So you’re ready to add CBD oil to your hair care routine. 

But you might be wondering… 

How To Use CBD Oil For Hair?

Some ways to use CBD oil for hair include:

  • Apply directly to the scalp: The most effective way is to apply CBD oil straight to your scalp. Massage a small amount of CBD oil directly onto your head and leave it for a few hours before washing it. 
  • Mix with shampoo or conditioner: Don’t want to apply CBD oil directly to your scalp? Add a few drops of hair oil to your shampoo or conditioner and use it.  

P.S: The benefits discussed above were based on studies involving direct CBD hair oil application. The effects may be reduced when CBD oil is diluted with another hair care product. 

  • Food consumption: Adding CBD oil to food or taking CBD edibles (like CBD gummy supplements) can contribute to overall hair wellness. But this won’t have a strong effect as a direct application.

How To Choose The Right CBD Product

Some things to consider when picking a CBD product include:

P.S. Full spectrum products contain THC and are illegal in the UK

  • Certificate of Analysis: Look for products with a certificate of analysis (CoA). A CoA is issued by an accredited laboratory, verifying whether the product is safe to use.
  • CBD content: Check how many milligrams of CBD are in each product serving. If you’re new to CBD treatment, start low and go slow until you find your optimal dosage
  • Reputable brands: Look for trusted and transparent brands. Also, consider products with positive customer reviews or awards. All these indicate high-quality CBD hair products.

6 FAQs About CBD Oil For Hair

Here are some common questions about CBD oil hair treatment: 

1. Are There Any Side Effects To Using CBD Oil?

CBD products are generally considered safe to use. 

However, if taken in extremely high doses (more than 100mg/day), CBD can cause: 

  • Nausea
  • Fatigue
  • Diarrhea 
  • Changes in appetite
Read more: Here is some important information about CBD Oil Side Effects and how to avoid them. 

2. Does CBD Make You Feel High?

Unlike THC, CBD will NOT make you feel high. 

Here’s the deal:

CBD is extracted from the cannabis plant and has mild psychoactive properties, but it’s a non-intoxicating cannabinoid.

The cannabinoid is usually extracted from the hemp plant — a cannabis plant variety with low concentrations of THC (less than 0.2%). 

3. What Is The Difference Between Hemp Oil And CBD Oil?

Both hemp oil (aka hemp seed oil) and CBD oil are extracted from the Cannabis sativa plant. 

Here’s how they differ:

  • Hemp seed oil is extracted from the hemp plant’s seeds and has almost no useful cannabinoids. But it contains plenty of essential fatty acids and nutrients.
  • CBD oil comes from the plant’s leaves, stalks, and flowers. It’s rich in beneficial cannabinoids, unlike hemp oil. 

CBD is often combined with hemp seed oil or coconut oil to create CBD oil products. 

4. How Do I Work Out My CBD Dosage?

CBD dosage may vary from person to person depending on factors like: 

  • Your body weight
  • CBD content
  • CBD product type 

According to recent research, topical application of 3-4mg of CBD every day for six months increased hair growth by a whopping 93.5%.

5. Can CBD Oil Be Used To Treat Alopecia? 

Alopecia is an autoimmune disorder that causes scalp inflammation and severe hair loss. 

It could be genetic or caused by factors like high stress and anxiety levels.


CBD may not directly treat alopecia. 

But it could help reduce alopecia symptoms like inflammation (due to CBD’s anti-inflammatory properties). 

Plus, CBD could reduce the severity of stress-induced alopecia due to its stress and anxiety relief properties.

6. Are There Any Other Alternative Hair Treatments I Can Try?

Proper hair treatment and a healthy diet are vital elements of a holistic hair care regime. 

Consider incorporating these habits and supplements into your daily routine: 

  • Eat a protein-rich diet: Eating foods high in protein, antioxidants, calcium, and omega-3 fatty acids (like eggs and fish) will improve your hair health
  • Take vitamin supplements: A deficiency in zinc and vitamins A and E can lead to hair loss. Try taking a multivitamin supplement in the morning
  • Hemp seed oil: Hemp seed oil is a great hair care product —  it contains essential fatty acids, vitamin E, amino acids, and high amounts of zinc. 
  • Use spironolactone pills: Spironolactone is a prescription medication for people with alopecia (an autoimmune disorder that causes hair loss). It can slow down the production of androgen — a hormone that contributes to hair loss. 
  • Try topical tretinoin: Tretinoin promotes cell development, which is essential to healthy hair growth. Try applying a tretinoin product to your wet hair while showering.
Quick Tip: Check these helpful guidelines for alopecia management from Harvard researcher and dermatologist Neera Nathan.
