Herbal remedies were used to treat hair loss in ancient Indian, Chinese, Egyptian, Arabic, and Greek medical systems.
Natural vegetable oils, such as rosemary essential oil, promote blood circulation in the scalp and have strong antioxidant properties. They have always been considered to have the potential to treat hair loss. Another example is that the tea polyphenols contained in green tea can inhibit 5-alpha reductase. It has a good effect on treating androgenetic alopecia.
Nutri Avenue found several vegetable oils that can effectively improve hair loss. Let’s take a look at what ingredients are working towards hair loss.
Focus On Improving Hair Loss: Pumpkin Seed Oil & Saw Palmetto
Pumpkin Seed Oil
This natural oil is rich in vitamin B, vitamin E, zinc, iron, copper, magnesium, selenium, unsaturated fatty acids, etc. Among them, zinc not only participates in the synthesis of many enzymes but also promotes the metabolism of male hormones.
Pumpkin seed oil can also reduce the activity of 5α-reductase in the human body. Reducing the activity of 5α-reductase prevents the male hormone testosterone (T) from being converted into dihydrotestosterone (DHT). It reduces the damage caused by DHT to men’s sensitive hair follicles and helps alleviate hair loss symptoms in patients with male pattern baldness.
It is a natural plant that grows in North America. It is used to treat prostate and urethritis in men. At the same time, it can also prevent the production of DHT, the cause of male hair loss.
In 2012, a study divided 100 male alopecia patients into two groups. One group received 320 milligrams of saw palmetto extract daily, and the other group received 1 milligram of finasteride per day. After 24 months, it was clinically observed that 38% of the saw palmetto extract group had a slight increase in hair density, and 68% of the finasteride group had an improvement. Finasteride affects both the forehead area and the crown of the head, whereas the effects of the saw palmetto group are generally felt on the crown of the head. 
This plant extract is naturally lipophilic and equal to hormonal supplements. It can metabolize products without causing damage to hair follicles. It can also promote the restoration of hair follicles, improve hair quality, and reduce scalp sensitivity to stimulation and pressure.
Saw palmetto can be used in many ways. There are shampoos abroad that specifically contain one ingredient named saw palmetto. Saw palmetto compound health supplements can also be taken orally.
Focus On Improving Hair Quality: Coconut Oil & Olive Oil
It is widely used in hair care because of its ability to penetrate deeply into the hair strands, providing rich nutrition and moisture. The small molecular structure in coconut oil allows it to penetrate the surface and interior of the hair. It can repair damaged hair and make hair softer and shiny.
It contains lauric acid. It is a fatty acid that helps protect hair. It protects hair roots and prevents hair breakage. Plus, along with the vitamin E in coconut oil, it also forms a protective layer that protects your hair from environmental aggressors and chemical treatments. It can protect hair from external factors such as sunlight, heat, pollution, and chemicals, reducing damage and breakage.
Secondly, coconut oil has natural moisturizing properties. It locks moisture in the hair and reduces moisture loss, thus preventing the hair from becoming dry and brittle. Keeping your hair well hydrated is important to keep your hair healthy and reduce breakage and hair loss.
Olive oil is not only a natural ingredient but also a great hair care ingredient.
- It reduces dihydrotestosterone (DHT) production.
DHT production is one of the biggest reasons for hair loss. This hormone attacks hair follicles, weakening them and causing hair loss. Regular use of olive oil helps to block the production of DHT, thereby helping to reduce hair loss.
- It prevents injury.
Free radicals are unstable molecules that cause cell damage. Antioxidants help stabilize free radicals and prevent damage. And Olive oil is rich in antioxidants. Therefore, it keeps your scalp and hair healthy and prevents damage.
- It nourishes and maintains hair.
The oil promotes blood circulation and provides essential nutrients and unsaturated fats to the follicles. It also helps lock in moisture in the hair shaft, preventing dryness and making hair more manageable.
- It reduces hair breakage.
Since this oil prevents hair from drying out, it can help keep hair thicker by reducing breakage. Additionally, it prevents hair loss by conditioning and strengthening the hair roots, which are rich in Omega-6 fatty acids.
- It soothes the scalp.
The oil has antifungal and antibacterial properties. Therefore, this helps relieve scalp itching, dandruff, and clogged hair follicles. Dandruff and clogged hair follicles are among the main causes of hair loss.
