ROSEMARY LEAF EXTRACT FOR HAIR GROWTH:
Mechanism of Action
Rosemary Leaf Extract is one of the active ingredients in Divi’s Scalp Serum.
This incredible plant extract, Rosemary Leaf Extract, offers a wealth of scalp-enhancing benefits, not least its ability to promote growth and treat certain forms of hair loss.
If you want longer, thicker, healthier hair and are shortlisting must-have ingredients for your next scalp care purchase, Rosemary Leaf Extract should be near the top of that list.
ABOUT ROSEMARY LEAF EXTRACT:
Rosemary is a perennial Mediterranean herb with a distinct peppery flavor and scent.
Mediterranean cultures have used rosemary rinses, oils and extracts in hair growth-promoting treatments for hundreds of years.
Recently, the scientific community has sought to find out whether rosemary actually does promote hair growth.
The results have been extremely positive, though the exact biological mechanisms behind rosemary’s growth-boosting effect are not yet fully understood.
*Rosemary Leaf Extract Stimulates Hair Growth
There’s been a whole lot of excitement around this humble plant in recent years – with good cause.
Unlike many growth-promoting ingredients, Rosemary Leaf Extract’s ability to boost scalp health and promote hair growth is well-documented.
*Improving Circulation
Boosting blood circulation in the scalp is one possible mechanism by which Rosemary Leaf Extract stimulates hair growth.
Though this effect hasn’t been observed during studies directly relating to hair growth, it has been demonstrated in one study featuring people who suffer from Raynaud’s Syndrome.
This condition causes poor circulation in the hands and feet.
During this study, Rosemary Leaf Extract was shown to improve circulation in these areas, possibly by stimulating the cells which line blood vessels (endothelial cells) and facilitating the movement of platelets.
Rosemary Leaf Extract may stimulate hair follicles and encourage hair to grow faster by improving circulation in the scalp.
Vasodilators like Rosemary Leaf Extract can also minimize shedding by ensuring new hair is thick, healthy and well-anchored in the scalp.
*Stimulating Nerve Function
According to the results of this study, hair and scalp care products containing Rosemary Leaf Extract may be especially beneficial to people who suffer from limited hair growth due to damage to nerve endings in the scalp.
The results show that a topical formulation containing rosemary oil was able to speed up tissue regeneration and rebuild nerve endings around hair follicles.
This action is thought to result from rosemary’s carnosic acid content, as this compound is known to have nerve-stimulating properties.
*Rosemary Leaf Extract to Treat Hair Loss
There is a great deal of evidence suggesting that serums, conditioners and shampoos containing rosemary oil or Rosemary Leaf Extract can stimulate hair growth in people with relatively healthy scalps.
There is also a growing body of research indicating rosemary may be able to treat hair loss and encourage new hair growth in people with androgenic alopecia.
The mechanisms by which Rosemary Leaf Extract can treat hair loss depend on the type of hair loss in question, or rather, its underlying cause.
Hair loss is far more prevalent than you might think; it affects around 85% of men and around 50% of women over 50 years of age.
Let's look at some of the most common causes of hair loss, and how rosemary may help with regrowth in each instance.
*Androgenic Alopecia
Androgenic alopecia (male- or female-pattern baldness) is thought to be caused by an androgen (a hormone that causes the development of male physical characteristics), called Dihydrotestosterone, or DHT.
An enzyme called 5-alpha-reductase converts testosterone into DHT and is directly responsible for the amount of DHT circulating in the bloodstream.
Androgenic alopecia occurs when excess DHT binds to receptors in hair follicles, causing them to shrink and eventually stop functioning.
A 2015 study sought to measure Rosemary Leaf Extract’s effect as an alternative treatment for people suffering from androgenic alopecia, and the results were extremely positive.
Researchers treated one group of test subjects with a topical rosemary oil formulation and the second group of subjects with the conventional hair loss treatment: minoxidil.
Following six months of treatment, both groups of patients had significant hair regrowth in previously balding areas of the scalp.
Rosemary Leaf Extract was found to be just as effective as conventional medical treatment.
Plus, the people treated with rosemary oil suffered far less scalp irritation due to this regrowth.
Prior to this 2015 study, a clinical review highlighted rosemary as a possible treatment for androgenic hair loss.
This review focused on rosemary oil rather than Rosemary Leaf Extract, but the findings were equally positive.
It’s thought that rosemary may treat male- and female-pattern baldness by blocking the DHT precursor, 5-alpha-reductase.
*Alopecia Areata
Alopecia areata is a type of autoimmune hair loss which occurs when the immune system becomes overactive and begins to attack the body’s own tissues, namely the hair follicles.
As a potent anti-inflammatory, Rosemary Leaf Extract may treat autoimmune hair loss by reducing inflammation around the hair follicles.
*Telogen Effluvium
Telogen effluvium is an extremely common form of hair loss occurring when the hair growth cycle is shortened, leading hair to shed excessively.
The condition can develop following periods of trauma or psychological distress and is often caused by stress-induced inflammation.
Telogen effluvium is reversible and may be improved with regular use of products containing Rosemary Leaf Extract, which are designed to reduce inflammation in the scalp.
*Scalp Folliculitis
Scalp folliculitis is characterized by an overgrowth of Staphylococcus Aureus, a bacteria naturally present on healthy scalps.
When the condition occurs, bacteria penetrate the scalp through a wound or open hair follicle, leading to irritated, inflamed bumps and increased hair fall.
Rosemary Leaf Extract contains camphor, an antibacterial compound.
Topical application of formulations containing camphor have been shown to treat scalp folliculitis by eliminating the bacterial overgrowth behind the condition.
If you suffer from scalp folliculitis and have experienced excessive hair shedding as a result, using scalp and hair care products containing Rosemary Leaf Extract may heal your scalp and facilitate natural hair regrowth.
*Scalp Psoriasis and Seborrheic Dermatitis
In psoriasis and seborrheic dermatitis, hair shedding is accelerated by both scratching and an overgrowth of certain fungi on the scalp.
This 2017 study shows Rosemary Leaf Extract may be an effective antifungal agent, implicating it as a possible treatment for hair loss caused by these conditions.
Products containing Rosemary Leaf Extract can also soothe the irritation associated with scalp conditions like psoriasis and seborrheic dermatitis.
This scalp-soothing effect is likely attributable to borneol, a compound in rosemary with topical analgesic properties.
By alleviating irritation, products containing rosemary support overall scalp health, promote healing, and allow hair to regrow.
*Rosemary Leaf Extract for Longer, Stronger Hair
If you struggle to grow your hair past a certain length, the cause could be your hair becoming brittle due to styling, chemicals, and other environmental factors, and breaking off prematurely.
Rosemary Leaf Extract is renowned for its ability to promote strong, resilient hair.
Products containing Rosemary Leaf Extract, like Divi’s Scalp Serum, can give the illusion of hair growing faster by minimizing breakage.
This, combined with rosemary’s hair follicle stimulating effect, can help you achieve long, luscious locks in the shortest possible time.
OTHER BENEFITS OF ROSEMARY LEAF EXTRACT FOR HAIR:
Products containing Rosemary Leaf Extract offer a whole host of cosmetic benefits besides enhanced scalp health and hair growth.
These are definitely worth mentioning, as growing longer, thicker hair is only part of the equation; the ultimate dream is to have longer, thicker hair rich in color and radiant with health.
ROSEMARY LEAF EXTRACT FIGHTS PREMATURE GRAYING:
Studies show Rosemary Leaf Extracts display antioxidant activity when taken internally or used topically.
Antioxidants are substances that combat the effects of oxidative stress caused by rogue molecules called free radicals, which can cause cells to age prematurely.
The compounds responsible for rosemary’s antioxidant activity are thought to be carnosol, carnosic acid and rosmarinic acid.
These compounds appear to accumulate in the fatty membrane surrounding skin cells, blocking unwelcome free radical activity.
Protecting hair follicles from free radical damage may help prevent premature graying caused by oxidative stress.
ROSEMARY LEAF EXTRACT FIGHTS DANDRUFF:
Herb extracts like Rosemary Leaf Extract may be able to combat dandruff and soothe itchy, flakey scalps via several mechanisms.
Studies show that topical application of Rosemary Leaf Extract as an essential oil can reduce flaking; likely, this effect is primarily due to the herb’s antifungal properties, as fungus on the scalp is a known aggravator.
Rosemary Leaf Extract’s analgesic properties may also play a part by reducing irritation and eliminating the urge to scratch.
HEALTH CONSIDERATIONS OF ROSEMARY LEAF EXTRACT:
Rosemary oil can act as an irritant and may not be suitable for people with sensitive skin.
If either of these issues affect you, it may be better to avoid the essential oil and stick to professionally formulated products containing Rosemary Leaf Extract.
Keep in mind that the information provided here should not be taken as a substitute for professional medical advice.
BEST WAY TO USE ROSEMARY LEAF EXTRACT FOR SCALP HEALTH:
If you’ve been researching Rosemary Leaf Extract and are thinking of factoring it into your hair and scalp care routine, you have probably encountered numerous blogs and videos promoting DIY rosemary oil sprays and rosemary extract distillations.
Remember, a lot can go wrong with these kinds of homemade treatments; rosemary oil is extremely potent and can damage the skin if not properly diluted in a carrier oil.
Plus, there is no guarantee that DIY treatments will be able to provide a consistent dose of rosemary’s active compounds in each application.
The best way to use rosemary for scalp health and to promote hair growth is to leave it to the professionals.
Divi’s Scalp Serum is carefully formulated in a clean laboratory environment with Rosemary Leaf Extract and other high-quality ingredients.
As a result, this product represents a safe and effective way to leverage Rosemary Leaf Extract’s many growth-promoting properties.
USE AMOUNT OF ROSEMARY LEAF EXTRACT:
This herb is 36 times more potent than fresh Rosemary Leaf Extract so to create a single strength liquid extract you would add 2.8g of herb to 97.2g of water and then filter it.
You could use that water as-is in your formula (so as your water phase) or you could take that single strength liquid and add it into your formula at any percentage.
SOLUBILITY OF ROSEMARY LEAF EXTRACT:
Rosemary Leaf Extract has a low degree of water solubility as supplied and may produce a cloudy-ish solution indicative of the fact that the extract won’t fully solubilise.
We recommend, in most situations, to prepare your herb into a demineralised water and alcohol mix (20% alcohol, 80% water) then filter out any residue before adding Rosemary Leaf Extract to your product.
HEAT STABILITY OF ROSEMARY LEAF EXTRACT:
Rosemary Leaf Extract is very high.
You could use Rosemary Leaf Extract as your water phase in an emulsion and heat it but it is more typical to use this as an extract and add it at the end of manufacturing.
