A Complete Guide To The Science Behind Our Formula
A Complete Guide into the Science Behind Our Evidence-Backed Formula
The story of how we formulated our unique blend
The story of Buff Hair started with a problem. Our founder, Jon, like millions of guys, was struggling with hair loss. He was ready to try pretty much anything to slow the shedding and get his confidence back, but the side effects he experienced from common hair loss medications had other plans. So, he started looking into alternatives, but found that most products in the market promised the world, cost the earth, yet didn't do much for his hair. To top it off, many of the men's hair growth products had some pretty awful ingredients, even when they were marketed as being 'natural'.
Jon wasn't going to give up that easily. The thing is, he's a logical guy. He’s skeptical, and evidence-obsessed - you probably know a guy just like him! He may not be the life of the party but he’s thorough, analytical, loves science, and optimises literally everything in his life. You could say his hair had become a fixation.
There’s no magical ‘and suddenly it came to him’ moment in this story. Instead, there’s a pretty boring part of months and months of staying up late reading research papers, pestering friends in the medical field, and spending way too much money on ordering stuff online.
It’s that boring part though, that’s the DNA of Buff Hair. No magic pill or top-secret recipe, just a blend of six, all-natural ingredients that each had to work hard to deserve their spot in the mix.
So here it is, the result of years of experimentation and a whole lot of science bottled into each Buff Hair serum we ship out.
Rosemary Oil | The Growth Stimulator

Boosts Scalp Circulation
Increases blood flow to hair follicles, ensuring optimal nutrient delivery for stronger, healthier growth.

Stimulates Hair Follicles
Encourages dormant follicles to reactivate, leading to visibly thicker and fuller hair over time.


Fights Hair Loss
Inhibits 5-alpha-reductase, the hormone behind male pattern baldness, and fights follicle-damaging free radicals.

Antibacterial & Antifungal
Soothes scalp irritation and combats dandruff, creating the ideal environment for hair growth.
What Does Rosemary Oil Do for My Hair?
A bioactive powerhouse for hair growth
Rosemary oil is one of the most powerful, clinically-recognised natural ingredients for fighting hair loss and stimulating hair growth. It’s no secret that there are many popular hair products that use rosemary oil alone as the active component. So, how does it benefit our hair?
Rosemary oil works in multiple ways to promote hair growth and fight hair loss: it improves blood circulation to the scalp, stimulates hair follicles, has anti-inflammatory effects, fights follicle-damaging free radicals, reduces scalp irritation, and has even been shown to inhibit 5-alpha-reductase activity, a key reason behind male pattern baldness.
Scientific Studies on Rosemary Oil
A 2015 randomised comparative trial found that rosemary oil was as effective as 2% minoxidil in increasing hair count over six months, with less scalp irritation.
Research has shown that rosemary oil can inhibit 5-alpha-reductase activity by up to 94.6%, similar to finasteride, an essential mechanism for treating androgenic alopecia.
A 2020 study reported that rosemary oil was as effective as 2% minoxidil ointment in treating androgenetic alopecia (male pattern baldness), with better treatment adherence.
Pumpkin Seed Oil | The DHT Blocker

Inhibits DHT Production
Blocks DHT, the hormone responsible for hair loss, helping to maintain follicle health.

Nutrient-Rich Formula
Packed with essential fatty acids, vitamins, and minerals that support hair strength and growth.


Improves Scalp Health
Soothes inflammation and promotes a balanced scalp environment for optimal hair growth.

Proven Hair Growth Benefits
Studies show pumpkin seed oil can increase hair count by 40% over 24 weeks.
What Does Pumpkin Seed Oil Do for My Hair?
A natural DHT blocker for combating hair loss
Pumpkin seed oil has shown promising results in promoting hair growth and treating hair loss, particularly in cases of androgenetic alopecia (pattern hair loss). One of the main causes for genetic, male pattern hair loss is a hormone called Dihydrotestosterone (DHT). In a nutshell, DHT causes follicles to shrink, leading to hair thinning and eventually baldness. Pumpkin seed oil has been shown to inhibit DHT, which is precisely why it’s one of the key components of Buff Hair.
Scientific Studies on Pumpkin Seed Oil
A 24-week study on men with mild to moderate androgenetic alopecia found that oral supplementation with 400 mg of PSO daily led to a significant increase in hair count compared to a placebo group.
A 2021 randomised comparative trial on women with female pattern hair loss (FPHL) compared topical PSO application to minoxidil 5% foam over three months. Results showed PSO treatment led to a significant decrease in hair shaft diversity and an increase in upright regrowing hairs.
A 2018 study published in the Journal of Cosmetic Dermatology found that topical PSO could reverse testosterone-induced hair growth retardation in mice, suggesting its potential as a topical treatment for male pattern baldness.
Another study on mice, conducted by Cho et al., demonstrated that topical application of PSO promoted hair growth, suggesting its promise as an alternative treatment for male pattern alopecia.
Vitamin E | The Protector

Deep Scalp Hydration
Helps lock in moisture, preventing dryness and promoting a nourished, healthier scalp.

Antioxidant Protection
Neutralises free radicals, reducing oxidative stress that can lead to hair follicle damage and thinning.


Improves Scalp Circulation
Can help blood flow to the scalp, supporting better nutrient delivery to hair follicles and healthier hair growth cycles.

Strengthens Hair Shaft
Supports cell membranes, enhancing hair strength and elasticity, reducing breakage and keeping hair smooth and resilient.
What Does Vitamin E Do for My Hair?
A cell-renewing antioxidant shield for stronger, healthier hair
Vitamin E is a powerhouse ingredient that supports healthy hair growth by enhancing microcirculation in the scalp and delivering essential nutrients to hair follicles. Its antioxidant properties help protect against oxidative stress, a known contributor to hair thinning and follicle damage, while strengthening the hair shaft to reduce breakage and shedding.
Scientific Studies on Vitamin E
A 2010 study involving 38 volunteers with hair loss found that supplementation with tocotrienols (a form of vitamin E) resulted in a 34.5% increase in hair count after 8 months, compared to a 0.1% decrease in the placebo group.
Some research suggests that vitamin E's antioxidant properties may help reduce cell damage and improve hair growth.
Improved blood circulation: Vitamin E aids in blood circulation, potentially enhancing nutrient delivery to hair follicles.

What Does Jojoba Oil Do for My Hair?
A sebum-mimicking hydrator that nurtures scalp health
Much like fertilisers help the soil grow plants, jojoba oil helps the scalp create ideal conditions for hair growth and hair loss prevention. Jojoba oil has a very unique composition, as it closely resembles human sebum, allowing it to effectively moisturise and nourish the scalp without causing excessive oiliness. A healthy scalp, in turn, has been scientifically proven to promote hair growth and reduce loss.
Scientific Studies on Jojoba Oil
A 2024 dermatological review confirmed jojoba oil's effectiveness as a moisturiser for skin and hair.
Research has shown jojoba oil's anti-inflammatory properties, which could benefit scalp conditions.

What Does Castor Oil Do for My Hair?
A deeply penetrative oil that fortifies roots and reinforces hair shafts
The use of castor oil for hair care dates all the way back to ancient times, with earliest records traced to ancient Egypt. For centuries, castor oil has been used for hair growth by cultures around the world. Castor oil has anti-inflammatory and anti-microbial properties and its molecular structure helps seal hair cuticles while improving shine.
Scientific Studies on Castor Oil
The oil's molecular structure helps retain moisture, which can protect the hair shaft and reduce breakage.
Castor oil is incredibly rich in ricinoleic acid: This omega-6 fatty acid makes up about 85-95% of castor oil and has anti-inflammatory properties, which may contribute to a healthier scalp environment, potentially supporting hair growth.
A 2019 study confirmed that castor oil applied on the scalp and hair stimulates blood circulation, fights fungal and bacterial infections, reduces dandruff, and locks moisture in the hair strands.

Batana oil has a rich history in hair care that spans centuries. The indigenous Miskito people of Honduras, also known as the "Tawira" or "people of beautiful hair," have been using batana oil for generations, referring to it as "liquid gold" due to its perceived benefits for hair health. Rich in fatty acids and antioxidants, batana oil helps create a healthier environment for hair growth and reduces breakage.
Scientific Studies on Batana Oil
Batana oil contains acids (oleic, palmitic, linoleic, and stearic acids) that can help moisturise hair and scalp.
