Hair loss affects everyone in varying degrees with up to 100 strands of loss per day considered normal. Higher amounts of hair loss are not typical and may have hereditary, hormonal, or stress-related causes. Some who experience hair loss try shampoos or creams to stimulate regrowth.
CBD oil has frequently been in the press for its purported soothing effects on pain and anxiety. As with any trend, some people are making claims that can’t be supported. CBD oil for hair loss is one of them. There are some online claims that research shows CBD is great for hair loss. The problem seems to be a lack of understanding about the difference between CBD oil and hemp seed oil.
Let’s separate CBD from hemp seed oil. The former is a cannabinoid found in the trichomes of the cannabis plant. CBD can be derived from marijuana or hemp. Hemp seed oil, however, comes from the seed of the hemp plant. The amino acids and fatty acids necessary for hair growth are found in hemp seeds, not CBD oil, according to Dr. Adie Wilson-Poe, a neuroscientist at Legacy Research Institute, specializing in cannabis pharmacology.
Amino acids (dubbed the building blocks of protein) and fatty acids are essential to hair growth and can be found in abundance in hemp seeds. The same omega-3s and omega-6s that make foods like salmon and walnuts healthy options also play a role in nourishing the hair.
The following studies expand on these ideas to show how CBD oil may help slow or stop hair loss.
A 2014 study conducted at the University of Seville in Spain found that hemp seed oil contains optimal levels of omega-3 and omega-6 fatty acids, which can facilitate hair growth. Researchers also found other essential fatty acids in hemp seed oil, including linoleic and gamma linoleic acids. Finally, researchers noted the presence of minerals such as calcium, phosphorus, magnesium, and potassium, all of which may enrich hair health. It’s important to note that this research pertains to essential acids in the diet, not topical applications, and the study focuses on beneficial components of hemp seed oil in general, not specifically for hair loss.

In 2018, a group of scientists examined the chemical profiles of hemp seeds in a comprehensive study published in the journal Molecules. Researchers found that hemp seeds contain many biologically active compounds that could boost hair health, including the previously identified omegas as well as a range of vitamins. Orally ingested hemp seeds may contribute to a balanced diet that is high in these beneficial fatty acids.
What the experts say
Dr. Wilson-Poe says, “There is no evidence to support that either oral or topical cannabinoids are effective for moisturizing the scalp or ameliorating hair loss.”
The Belgravia Centre in London treats individuals dealing with hair loss. According to hair experts at the center:
“. (CBD) may help to improve the condition of the hair in the same way following a balanced, healthy diet would. However, CBD oil is highly unlikely to treat a medical hair loss condition, especially if this is a genetic complaint – namely Male Pattern Baldness and Female Pattern Hair Loss, both of which cause thinning hair anywhere in the vertex area from the crown to the hairline, in those affected.”
CBD shows promise for a number of applications but treating hair loss is not one of them. Hemp seed oil can’t do all the things CBD seems to but it does provide vitamins and essential acids that support overall health, including healthy hair.

CBD Helped Me Manage Anxiety—and Stress-Induced Alopecia
Sitting in my parked car, I looked at the clock. Five minutes until my watercolor painting class began. Here goes nothing. I unscrewed the small bottle of cannabidiol oil in my hands and scraped the sides of the dropper on its neck, watching the excess thick oil slide off. I held the dropper above my mouth and carefully let one drop plop onto my tongue like a raindrop. The oil tasted like the earth, piney and unsweetened.
I paused for 30 seconds and repeated the process five times. Then I got out of my car to sit in a three-hour-long art class.
In class, I stared at the clock, waiting to suddenly feel high or to officially debunk a wellness fad. It had been 15 minutes. Now 20. Sometime between 20 and 30 minutes, I noticed how the watercolor paints beautifully swirled in my water cup, something I usually don’t pay attention to. As I painted, I wasn’t held back by my typical fear of not doing a good job. I just let my hands move, totally enjoying myself. It was a subtle shift into the present moment, significant for someone with anxiety.
That evening, about three months ago, was my introduction to CBD oil, a hopeful solution to managing my stress and anxiety, which hit their pinnacle (or is the better way to phrase it, rock bottom?) earlier this year. Talking to my friends, family and even a therapist were no longer enough to handle the anxiety I was recently going through. It was unprecedented, even for me.
Back in February, I was getting ready to shower when I ran my hands through the back of my hair and touched something fleshy, smooth, and just not right. I asked my sister to take a look at it and she gasped. It was a dollar-sized bald spot caused by alopecia areata, an autoimmune condition where your immune system attacks your hair follicles. It is believed to be triggered by stress (or at least, stress doesn’t help it). At the time, I was in the middle of interviewing for a dream job (that I ultimately didn’t get, but alas consumed me anyway), struggling with my social relationships, and overall pretty unhappy in New York. I guess you can say I was stressed.
So, I accepted a different job and moved to Hawaii. I started taking a drugstore amount of supplements (Vitamin D, Biotin, B-12 Complex, the list goes on), signed up for a yoga membership, and added a meditation app to my bedtime routine. I was also prescribed an antidepressant, but forwent taking it when I read accounts of other patients noticing rapid hair loss while on it.
Still, nothing worked. Over the next few months, I continued to shed hair—and my confidence. I ended up with a total of about 13 spots of various sizes on the back of my head and around the top of my head. “You need to relax,” my dad kept saying.
Here’s the kicker: Having alopecia areata is extremely stressful in and of itself, and it provides a horde of new things to stress about. I examined my pillow every morning for stray hairs and oh god, maybe eyelashes. I dreaded washing my hair, counting every strand that came out when I rinsed. With a tendency to spiral, I found myself crying about the alopecia at work, on the bus, at home—anywhere I was reminded of my current situation, which was kind of everywhere. What if the spots on the back of my head combine into one impossible-to-cover monster? What if I lose all the hair at the top of my head, how ridiculous will I look? Who would date me? Is my spot showing? Did my coworker see it? Then I felt guilty for caring about something so cosmetic.
On a thread in an alopecia areata subreddit, people kept mentioning CBD oil as a useful tool for helping them relax. Turns out, they might be onto something. ”
It was like a wake-up call that whatever I was doing was not enough for handling my anxiety. I needed to try something different. On a thread in an alopecia areata subreddit, people kept mentioning CBD oil as a useful tool for helping them relax. Turns out, they might be onto something.
According to Brook Henry, an assistant research scientist at the University of California, San Diego’s Center for Medical Cannabis Research and department of psychiatry, there are a number of reports in rats and humans showing CBD as effective at decreasing anxiety by reducing activity in areas that are known to induce anxiety, such as the amygdala. Unlike its cousin, THC, which I’m more familiar with, CBD has no psychoactive effects and doesn’t really affect one’s physiological function (or that sometimes paranoid feeling of being high.) This is why so many people are turning to CBD for anxiety.
“One could describe CBD is the ‘kinder, gentler’ cousin of THC; they are similar in many respects and may both help to reduce pain and inflammation, but heavy or long-term use of THC could have significantly greater negative effects,” Henry tells me.
In other words, it was worth a shot. I spoke to my doctors and therapist and bit the bullet and invested in a tiny but expensive bottle of CBD oil from my local hemp shop, which led me to my first dosing in art class. That night was the first in a long time when I was just present in what I was doing, unanchored by those anxious what if questions. From that evening on, I’ve been experimenting with dosage and timing, using it when I feel an uneasy day coming on or if I’m nervous about an upcoming event.
It’s an understated shift from a buzzing brain into a contently silent one—as if someone just lowered the volume on my internal thoughts. It’s become a staple in my mental health repertoire.
I know that CBD is not the cure-all to instantly zapping away a downward spiral or anxiety, but those subtle moments of chilling out help me remember that mental tranquility is out there even if my bottle is not around.
As for my hair, well, time has passed and with my toolbox for relaxation larger than ever, my many little spots now sport many little baby hairs. I haven’t noticed it too much though, or at least I’ve been pretty chill about it.
