Pumpkin Seed Oil vs Avocado Oil for Hair Growth: Reviews, Benefits & Side Effects
BY TRYBELLO
Nov 11, 2025

Key Takeaways
- Pumpkin seed oil has strong clinical evidence for promoting hair growth by blocking DHT, with studies showing up to a 40% increase in hair count after 24 weeks.
- Avocado oil excels at deep moisturizing and strengthening hair while improving scalp health, though it lacks direct clinical proof of hair growth stimulation.
- Pumpkin seed oil is ideal for addressing hormone-related hair loss, while avocado oil works best for dry, damaged hair needing repair and hydration.
- Both oils have minimal side effects, but pumpkin seed oil may cause skin irritation in sensitive individuals, while avocado oil can weigh down fine hair.
- Trybello products combine clinically-proven natural ingredients to address multiple causes of hair loss simultaneously, delivering visible results in as little as 2 months.
Natural Oils for Hair Health
Natural oils have been used for centuries to promote hair health, and modern science is finally catching up. These oils work by delivering essential fatty acids, vitamins, and antioxidants directly to your hair follicles and scalp. They moisturize dry strands, reduce inflammation, protect against environmental damage, and in some cases, even influence the hormonal pathways that affect hair growth.

What Is Pumpkin Seed Oil?
Pumpkin seed oil is extracted from the seeds of the Cucurbita pepo plant and has a rich, nutty profile packed with nutrients. This deep green oil is loaded with fatty acids, vitamin E, zinc, and phytosterols, plant compounds that can have powerful effects on your body.
What makes pumpkin seed oil particularly interesting for hair health is its potential to block DHT (dihydrotestosterone), a hormone that causes hair follicles to shrink and eventually stop producing hair.

Pumpkin seed oil, rich in DHT-blocking phytosterols, showed a 40% increase in hair count in clinical studies.
Benefits of Pumpkin Seed Oil
The evidence supporting pumpkin seed oil for hair growth is impressive. A study published in 2014 found that men with mild to moderate pattern hair loss who took 400 mg of pumpkin seed oil daily experienced a 40% increase in hair count after 24 weeks. In comparison, the placebo group only saw a 10% increase.
The oil's vitamin E content provides antioxidant protection, shielding hair follicles from oxidative stress that can damage cells and impair growth.
Potential Side Effects of Pumpkin Seed Oil
While pumpkin seed oil is generally well-tolerated, some people may experience mild skin irritation or allergic reactions, particularly if they have sensitive skin. If you have conditions like eczema or dermatitis, approach topical application with caution and consider doing a patch test first.
What Is Avocado Oil?
Avocado oil comes from the creamy fruit of the Persea americana tree and is celebrated for its moisturizing properties. Rich in vitamins A, D, E, biotin, lecithin, and fatty acids like oleic acid, this oil has become a staple in both culinary and cosmetic applications.
Unlike pumpkin seed oil, which targets hormonal pathways, avocado oil focuses on nourishing and protecting the hair and scalp, creating optimal conditions for growth.
Benefits of Avocado Oil
The biotin and folate naturally present in avocado oil are essential nutrients that support healthy hair development. One of avocado oil's standout features is its ability to penetrate the hair shaft. Unlike heavier oils that sit on the surface, avocado oil can actually get inside your hair strands, strengthening them from within and preventing breakage.
The antioxidants in avocado oil protect hair follicles from environmental damage and inflammation. A healthy, inflammation-free scalp is fundamental to consistent hair growth.

Rich in biotin and fatty acids, avocado oil penetrates the hair shaft to strengthen strands from within.
Potential Side Effects of Avocado Oil
Avocado oil is considered very safe, with allergic reactions being quite rare. However, people with latex allergies should be aware that they may be more prone to avocado sensitivity. Over-application can lead to greasy hair and potentially clogged follicles, especially for people with fine or naturally oily hair.
How to Use These Oils
Pumpkin seed oil can be taken as an oral supplement or applied topically to the scalp. For topical use, massage a small amount directly onto your scalp 2–3 times per week, optionally leaving it overnight for deeper absorption.
Avocado oil is typically used topically as a hair mask, pre-shampoo treatment, or leave-in conditioner. Apply it to damp hair, leave it on for 20–30 minutes, and then shampoo as usual. Some people also use small amounts as a finishing oil to tame frizz.
User Reviews
Pumpkin Seed Oil
Users report noticeable reductions in hair shedding within the first few weeks, often with less oily scalps. Long-term users appreciate having a natural DHT-blocking alternative without finasteride's sexual side effects, with those experiencing hormonal hair loss reporting modest improvements in thickness and density. Results require 3–6 months of patience, and some find effects modest compared to pharmaceutical treatments, with some seeing no improvement despite regular use.
Avocado Oil
Avocado oil is praised as an excellent moisturizer that makes hair noticeably softer and more manageable after just a few uses, working particularly well for thick, curly, and natural textures. It effectively reduces breakage and split ends while adding shine without coconut oil's heaviness, and helps with scalp dryness and dandruff.
It has a strong smell which can be off-putting and sometimes difficult to wash out. People with fine or thin hair types find that it weighs hair down and creates greasiness.
