Many hair loss suffers seek a natural alternative to hair regrowth prescription drugs. The Beta-sitosterol in saw palmetto shows remarkable hair growth-promoting activity.  A natural effective topical Saw Palmetto formulation is HAIRMETTO Saw Palmetto Oil. We researched this formulation and were impressed with what we found. It is a combination of natural ingredients scientifically proven to stop the contributing factors of hair loss and maximize hair growth potential in both men and women.
HAIRMETTO Saw Palmetto Oil is a natural formulation that blocks DHT and Androgens. It also stimulates hair follicles. Its namesake ingredient is Saw Palmetto.
Saw Palmetto is available as an oral supplement. HAIRMETTO Saw Palmetto Oil is applied topically directly only to the areas you need to it for best results.
For a topical formulation to stop hair loss or help hair grow, it must address the source of hair loss. This calls for understanding the relationship between hair loss and DHT.
Understanding DHT & Hair Loss
DHT (dihydrotestosterone) is a natural hormone that accumulates on the scalp.
DHT is the enemy.
DHT settles at the base of the hair follicle. It also accumulates under dandruff and dry flakes. If left unaddressed, DHT smothers the hair follicle and blocks protein absorption. DHT causes hair follicle shrinkage.  This deters new hair growth until the follicle doesn’t grow hair at all. While both men and women have DHT, testosterone elevates DHT levels in men.
How do you know your follicles are suffering from DHT build-up?
You can detect a struggling follicle by looking for shorter, thinner hairs on your head. The existing hair gets thinner and shorter until it sheds and another hair does not grow back in its’ place. When many follicles do this, hair becomes sparse in areas, exposing more scalp.
Can anything stop DHT?
A few natural ingredients are proven to remove DHT. Some also improve blood flow to kick-start hair regrowth.  Once DHT is removed and kept off the scalp, recently dormant follicles can grow hair again.
That is where HAIRMETTO Saw Palmetto Oil comes in. Let’s look at the ingredient list.
SAW PALMETTO (SERENOA REPENS)
Saw Palmetto comes from the berries of Serenoa repens, a small palm plant. It is a natural DHT blocker. Saw Palmetto is also a 5 alpha-reductase inhibitor. 5 alpha-reductase converts testosterone to DHT resulting in male pattern baldness. 
Saw Palmetto also inhibits the DHT receptors in the follicles. This limits the damage that any remaining DHT can do.
This formulation has 200mg of Saw Palmetto.
PUMPKIN SEED OIL (CUCURBITA PEPO)
Studies show that Pumpkin Seed oil inhibits DHT production. The oils’ phytosterols inhibit the conversion of testosterone to DHT in the scalp. Delta-7-sterine stops DHT from binding with hair follicles. 
Pumpkin seed oil also nourishes the scalp. It contains fatty acids, vitamins, proteins, and minerals.
It is high in polyunsaturated fatty acids and antioxidants. This maintains cell structure and moisture levels of the scalp and hair.
Pumpkin Seed Oil is high in Vitamin E and zinc to promote skin renewal.
Zinc reduces scalp issues such as seborrheic dermatitis, dry flakes, itching, and irritation.
Pumpkin Seed Oil is best used within a formulation rather than on its own.
This formulation has 4000mg of Pumpkin Seed Oil.
CASTOR SEED OIL (RICINUS COMMUNIS)
Castor Seed Oil has long been used to promote hair growth. No scientific studies to date correlate Castor Oil with hair regrowth or stop loss. Castor Seed Oil does remove some of the barriers that impede hair growth.
These barriers include scalp conditions such as scalp infection, chronically dry scalps, or other scalp inflammation. Castor Seed Oil contributes to the general moisture levels and health of the scalp. A healthy scalp is necessary to have an environment conducive to hair growth. Castor Seed Oil is rich in vitamins and fatty acids to nourish both hair and scalp.
Castor Seed Oil is a humectant. It temporarily plumps the hair with moisture for a fuller and healthier look. It also gives hair more flexibility, protecting new hairs and existing brittle hair. If you see breakage close to the hair root, brittleness can be a culprit and Castor Seed Oil can help.
Castor Seed Oil is an excellent base oil for the next three important ingredients.
A double-blind, evidence-based method study showed a mix of lavender, rosemary, and cedarwood extract (the next three ingredients in this formulation) reduced hair loss significantly amongst alopecia areata patients. 
Individually, each of these essential oils also benefits scalp health and hair growth:
Rosemary Extract stimulates and promotes better blood circulation to deliver the nutrients necessary to build collagen, elastin and to encourage scar repair.
It also has natural antiseptic properties and is a gentle exfoliant for dead skin flakes.
An exciting study demonstrated Rosemary Oil is as effective as Minoxidil for hair growth stimulation without the chemical side effects. Rosemary combats a specific type of hair loss, androgenetic alopecia.
Research shows massaging the scalp for six months with Rosemary oil and carrier oil is as effective as 5% Minoxidil at regrowing hair.
Another study found the 12-methoxycarnosic acid in Rosemary Extract a promising crude drug for treating male pattern baldness caused by 5Î±-reductase inhibition, or the testosterone conversion to DHT on the scalp. The study concluded “These results suggest that they inhibit the binding of dihydrotestosterone to androgen receptors”. 
Lavender’s anti-microbial and anti-bacterial properties keep the scalp healthy. It has soothing properties to calm any scalp imbalances such as inflammation or dry skin flaking. This is beneficial to remove places that DHT might accumulate.
The linalyl acetate in lavender enhances cell growth in skin and hair.
Some lab studies show promise in lavender inducing faster hair growth. 
Cedarwood extract is derived from the needles, leaves, bark, and berries of cedar trees.
Cedarwood reduces hair loss by balancing oil production.
It also has antifungal and antibacterial properties to keep the scalp healthy.
what it does NOT contain
This vegan formula has no:
- SLS (sulfates)
Clean & Green: CO2 Extraction
The natural ingredients in this formulation are harvested by CO2 Extraction. CO2 Extraction is a green technology which retains all the natural properties while eliminating any heavy metals and pesticides. CO2 Extraction doesn’t pollute the environment.
The Science of Pumpkin Seed Oil
I part my hair and apply the oil directly to hair roots with the nozzle tip and massage my scalp well.
It is left to absorb in overnight into hair shafts and roots. It is not a heavy viscosity but not watery either. It reminds me of the consistency of apricot oil.
It is not itchy or hair-clumping like many Minoxidil preparations.
I like being able to apply it just to the roots of sparser areas without covering my hair with greasy oil. I like that the nutrients are applied directly to my weaker follicles instead of circulating in my body and impacting other hormonal responses.
I don’t always like to wash hair daily. My hair is on the dry side, but the oil absorbed into my roots by morning. Oilier hair types might use bit of dry shampoo to re-fluff. There is no residue.
It smells faintly of lavender.
According to the American Hair Loss Association, 40% of women experience hair loss. Women have fewer options and many proven hair regrowth prescription drugs have side effect profiles undesirable for women . Hairmetto Saw Palmetto Oil provides a safe and effective way to naturally stop hair loss. The ingredients are all safe and nourish the scalp and hair. The correct proportions of scientifically backed ingredients come pre-mixed and the oil is exceptionally easy to use.
