Does weed (cannabis) make your hair grow? Here’s what you need to know

Many people believe that mixing weed into your hair cream or coconut oil and applying it to the scalp can promote hair growth.

However, is there any truth to this notion? Let's delve into the potential effects of weed on hair growth and what the science says.

The cannabis-hair growth connection

Cannabis, commonly known as weed, contains various compounds, the most notable being THC (tetrahydrocannabinol) and CBD (cannabidiol). These compounds have been studied for their numerous health benefits, but their effects on hair growth are not well-documented.

Potential benefits

1. Anti-inflammatory properties: CBD is known for its anti-inflammatory effects, which could help reduce scalp inflammation. A healthy scalp is crucial for hair growth, as inflammation can impede the hair growth cycle.
2. Stress reduction: Cannabis is often used to alleviate stress and anxiety. Since stress is a known factor in hair loss, reducing stress levels might indirectly support hair growth.
3. Improved blood circulation: Some believe that the application of cannabis-infused oils may enhance blood circulation to the scalp, potentially promoting hair growth. However, this claim lacks substantial scientific backing.

The myths

1. Direct hair growth stimulation: There is no concrete scientific evidence to suggest that cannabis or its compounds can directly stimulate hair growth. While it may have some benefits for scalp health, it is not a miracle cure for hair loss.
2. THC absorption: Applying THC-rich products to the scalp is unlikely to result in significant absorption that would affect hair growth. Most of the research on THC pertains to its psychoactive effects when ingested or inhaled.

Considerations

1. Legal status: Cannabis is still illegal or regulated in many countries. Ensure you are aware of the laws in your region before using cannabis-infused products.
2. Product quality: If you choose to experiment with cannabis-infused hair products, ensure they are from reputable sources. Poor-quality products may contain harmful additives that could damage your hair or scalp.
3. Allergic reactions: As with any new product, test a small amount on your skin before applying it to your scalp to ensure you do not have an adverse reaction.

While cannabis and its compounds have shown potential in various health areas, the evidence supporting their effectiveness in promoting hair growth is limited and largely anecdotal.

If you are experiencing hair loss, it is advisable to consult a healthcare professional to explore proven treatments and underlying causes.

In summary, the notion that weed can make your hair grow remains largely unproven. Focusing on a healthy diet, proper hair care, and stress management are more reliable ways to support hair growth.
