Pumpkin Seed Oil and DHT: Hair Loss Solution

As Halloween draws near, our thoughts might turn to carving pumpkins and displaying all manner of pumpkin themed paraphernalia in our windows!

But want to know what fascinates us at MONPURE most of all? Pumpkin seeds. (Yes, the ones which normally get scooped out and thrown on the compost!) Pumpkin seed oil is a great natural ingredient for minimising hair loss and boosting hair growth. But how?

Pumpkin Seed Oil Blocks DHT - A natural solution to prevent thinning and promote regrowth

Pumpkin seed oil scientifically proven to block DHT, while also stimulating the follicles and delivering nutrients to the scalp. This means that pumpkin seeds initially target the catagen and telogen phases of the hair growth cycle, working to minimise excess shedding. Similarly, it boosts the growth of new follicles leaving the telogen phase and entering into a new cycle of the anagen phase. Let's unpack the science.

The Importance of the Scalp

As you may know, MONPURE is all about treating scalp and hair issues with gentle, plant-based ingredients as opposed to using harsh synthetic chemicals (which can cause irritation and sometimes even make things worse). And pumpkin seed oil is one such gentle ingredient, which is actually brilliant for treating and preventing hair loss – which is why we’ve made it the star of our award-winning Follicle Boost Hair Density Serum.

Hair loss is something that affects many of us (40% of women will have some form of it in their lifetime), which can take its toll on our emotional health – especially if it’s noticeable. As our resident dermatologist Dr Sue Ann Chan advises, early intervention is key. “If you’re concerned about hair loss, it would be advisable to seek advice from a dermatologist to obtain appropriate diagnosis and medical treatment for your scalp, preferably at an earlier stage before it becomes advanced,” she says. 

“Maintaining a good scalp care regime, with targeted products such as those created by the scientists behind MONPURE, is so crucial to preventing these issues,” she adds. A common type of hair loss is female pattern hair loss – which is one of the issues our Follicle Boost Hair Density Serum was created to help treat.

“This is a genetic type of hair loss which can be encountered by women who are in their 30s and older, but most frequently occurs with menopause,” Dr Sue Ann explains. “It happens when the hair’s growth phase slows down and the hair follicles shrink. It usually takes the form of diffuse thinning, starting from the crown of the head, but unlike male pattern hair loss, it doesn’t result in complete baldness.” 

The Science of Pumpkin Seed Extract for Hair Loss

So where does pumpkin seed extract or pumpkin seed oil come into play? Well, one of the androgens responsible for female pattern hair loss is Dihydrotestosterone (DHT), which is a byproduct of testosterone (which increases as women get older). While DHT results in an increase in hair growth elsewhere on the body, it contributes to hair loss on the scalp, shrinking the hair follicle’s anagen (growth) phase and prolonging the telogen (shedding) phase. 5-alpha reductase is the enzyme responsible for converting 10% of testosterone into DHT – which pumpkin seed oil has been scientifically proven to help block, which is why it makes a real difference when it comes to preventing and treating hair loss. 

(A recent study of pumpkin seed oil supplements in Korea showed an increase in hair growth by 40% over the course of 24 weeks.)

If you’re keen to discover how pumpkin seed oil works wonders for your hair, try our award-winning Follicle Boost Hair Density Serum for yourself. It also contains other follicle-feeding ingredients such as rosemary leaf and coffee extracts – while exfoliating retinol and lactic acid work to improve cell turnover and remove dead skin and debris that often inhibit hair growth.
