Alopecia areata occurs when the body targets and harms its hair follicles. This can lead to hair loss anywhere on the body. However, the head and face are the two areas most likely to be affected by this condition.
Alopecia areata is never contagious and isn’t typically symptomatic of a more significant problem. Instead, alopecia areata is a condition itself. Most people experience this condition during childhood, but it’s possible for adults to also experience hair loss due to alopecia areata.
Individuals with this condition can have a range of hair loss, typically occurring in circular patches. Some people will have limited hair loss, while others may lose larger quantities. It’s estimated that 6.8 million Americans have this condition.
What Causes Alopecia Areata?
Alopecia areata is an autoimmune condition. However, a few factors can contribute to the onset of this diagnosis, such as a virus or substance. Chemotherapy treatment in cancer patients can also induce alopecia.1
There is typically a significant genetic component that leads to the development of this condition. This condition is polygenic, meaning both parents must pass on specific genes for the child to have alopecia areata.
If you use cannabis and have this condition, you may wonder: can weed cause hair loss? Research has not been able to provide a solid answer to this question.
Research demonstrates that cannabinoids like CBD may help promote hair growth,2 and it’s more likely that other factors play a more significant role in hair loss than cannabis. There’s still more to learn about cannabis and hair loss, but it’s unlikely that consuming this substance will significantly impact hair loss.
While no clear answer exists about cannabis and hair growth, cannabis will not cause alopecia areata. If you’re struggling with this condition, genetics will likely play a much more significant role than the consumption of cannabis.
Alopecia Areata Signs & Symptoms
Alopecia areata can be challenging to cope with. If you’re experiencing large amounts of hair loss, you may wonder if you have this condition. If you are experiencing alopecia areata, you may have one or more of the following symptoms:
- Oval or round hair loss patches,
- Itching,
- Burning,
- Hair that grows back and then falls out.
There are a variety of reasons why someone can experience hair loss. Losing a significant amount of hair does not necessarily mean you have alopecia areata, but it can still be concerning. If you’re struggling with hair loss, consider contacting a medical professional and sharing your symptoms.
Can Cannabis Help Alleviate Alopecia Areata?
There hasn’t yet been enough research to understand the correlation between cannabis and alopecia areata.
It’s possible that CBD could play an essential role in targeting hair follicles and encouraging hair growth. CBD can act as an important messenger that signals to various cells and may lead to the development of more productive hair follicles in certain doses.2
Another critical factor to discuss is the interaction between the immune system and cannabis. As was mentioned previously, alopecia areata results when the immune system views hair follicles as a threat. It’s possible that cannabis could help mediate this threat, as the compounds present in cannabis can interact with various immune system cells.3
One study examined the benefits of using cannabis for alopecia areata. While the results didn’t show significant hair growth for all participants, the researchers did note that cannabis improved the social components of this condition. Cannabis improved participant stress and depression, two things that can result from societal views of hair loss.4
Further research on the impact cannabis has on the immune system could provide important discoveries for those with alopecia areata and other autoimmune conditions.

Frequently Asked Questions About Cannabis & Alopecia Areata
There’s a lot that still needs to be learned about alopecia areata. These are some common questions about this condition.
Should I try a topical cannabis product to help with my hair loss?
There is no conclusive evidence that cannabis can help with hair loss from alopecia areata. However, if you choose to try cannabis, topical products can be a great way to address alopecia areata symptoms. They’re a great option because they can provide localized relief and address specific areas causing concern. Many people find topical products accessible and can be purchased at a local dispensary.
I’m feeling skeptical about using cannabis for hair loss. Should I still try it?
You should never use a product if you don’t feel comfortable with it. While cannabis can be an excellent option for some, it’s not the right choice for everyone. If you’re feeling unsure about whether cannabis could be right for you, consider doing some more research and speaking with professionals about your different options. If you don’t feel comfortable with using cannabis, then you shouldn’t.
I’ve heard good things about CBD and hair growth. Are the benefits true?
Studies have shown that CBD can be an effective way to encourage hair growth.2 It’s unlikely that using CBD would cause any negative impacts, so it’s a great way to explore benefits and see if a particular product is the right option for you. CBD oil for alopecia is a great first step to encourage hair growth.
I have hair loss, but I don’t know why. Is it worth trying cannabis?
Consider speaking with a doctor about your hair loss and any underlying causes that may be present. If a condition is causing your hair loss, cannabis may or may not be an effective solution.
