Allantoin

Allantoin is a chemical compound used in skin and hair products to heal, moisturize, and soothe.  It is also thought to promote healthy tissue formation and cell growth.

Allium cepa (onion)

Allium cepa (onion) is a plant used not only as food but also as a component in skin and hair health treatments.  Applied onto the scalp, onion is reputed to encourage hair health by stimulating blood circulation.  Onion also has anti-microbial characteristics that address scalp infections. The plant is abundant in sulphur, which boosts collagen production, thereby promoting hair thickness, strength, and growth.  It may help those who want to grow eyebrows back naturally while being careful to keep any onion juice away from the eyes (ouch!).

Aloe barbadensis

Aloe barbadensis is a plant used for food, medicine, and cosmetics.  It is also known simply as aloe.  The leaf juice has a variety of enzymes, vitamins, anti-microbial and anti-inflammatory agents, and amino acids.  These support hair growth by soothing, promoting healing, and eradicating any conditions that might be causing hair problems, by conditioning the scalp and hair, and by providing an optimal environment to grow eyebrows back.

Amar bel (see Cuscuta reflexa)

Amla (see Emblica offinalis)

Aminexil

Aminexil is a topical that promotes elasticity of collagen, thus improving circulation to the hair follicle. The improved blood flow is conducive to hair growth.

Aminexil complements minoxidil (Rogaine), and the two solutions can be used together topically. Both Aminexil and Minoxidil support hair growth, but in different ways.

Amino acids

Amino acids are the tiny building blocks of proteins. Together, many of these building blocks form long protein chains that can have many different shapes and functions.  Protein accounts for over 90 percent of hair fiber.

There are 20 kinds of amino acids, 9 of which the human body can’t produce on its own.  To have great skin and hair, it’s important to get enough protein in our diet.  Using amino acids topically (in creams and serums) can also improve the condition of hair and skin, according to clinical studies.  Some benefits of topically applied amino acids include:

  • protection from damaging UV light
  • antioxidant effects
  • conditioning of skin
  • boosting of tissue repair

Aminosaccharides

Aminosaccharides (“amino sugars”) are tiny building bits that provide material to maintain the body in and around certain cells.  Normally the amino sugars are made in the cells where they’re needed.  People can also get amino sugars through the diet.

Aminosaccharides can be applied on the skin for cosmetic purposes.  For example, N-Acetyl glucosamine (NAG) is necessary for production of hyaluronic acid in the skin, and NAG is known to reduce the appearance of dark spots on the skin.

Amla (see Emblica offinalis)

Anagen

Anagen is the active growth stage of an eyebrow hair. Cells in the root of the hair multiply and continue to add length to the hair shaft.  The length of this phase determines the length of the eyebrow hair.  The anagen phase lasts between 30 and 45 days.  Ingredients that trigger or prolong the anagen stage are ideal to help grow your eyebrows back.

Arctium lappa (burdock)

Burdock is a plant with a history of use in folk medicine for a variety of purposes. It’s considered to be a blood purifier and to have anti-inflammatory properties.  Burdock is rich in several items that promote healthy hair:  phytosterols, essential fatty acids, and amino acids.  These constituents are thought to support hair health by:

  • delivering nutrients to the hair roots through increased circulation
  • reducing scalp inflamation
  • keeping the scalp free of excessive oil and grease

Argania spinosa (argan) 

Argan oil is a traditional plant-based treatment for scalp problems that compromise hair health.  It has been used since ancient times to ease itchy, flaky scalp conditions that can clog hair follicles and lead to hair loss.  Argan oil can relieve symptoms of dermatitis, psoriasis, dry scalp, seborrheic dermatitis (oily scalp), and dandruff.  Argan oil is also used to enhance the appearance of hair by increasing control and shine.

Arginine

Arginine is an amino acid. It’s a precursor of nitric oxide. Nitric oxide enhances blood flow and improves nutrition available to follicles.  This improved environment allows for individual hair fibers to become thicker.  If you’re hoping to grow your eyebrows thicker, it might be a good idea to try a product formulated with arginine.

Arnica montana

Arnica montana is an herb grown mainly in northern India which contains phulin, tannin, volatile oil, and arnicin.  Arnica is often used to promote tissue healing, for example, after surgery.  It’s sometimes used in hair cleaning and conditioning products and anti-dandruff preparations to promote hair and scalp health.

Barberry is thought to cleanse the system, thus providing improved conditions for hair health.

Beta-sitosterol

Beta-sitosterol is a plant sterol.  It has a structure similar to cholesterol (which is found in foods derived from animals, such as meat and buter).  However, plant sterols can actually block absorption of cholesterol, giving plant sterols a reputation for promoting heart health.

Besides having this great benefit, plant sterols contain androgen-blockers that can block DHT, a hormone that contributes to hair loss.

Bhumi alma (see Phyllanthus niruri)

Biotin (vitamin B7)

Biotin is a water-soluble B-complex vitamin.  It’s an essential piece of our nutrition and can’t be produced by the human body.  The consensus seems to be that taking biotin by mouth (whether in food or supplements) will improve the condition of your scalp and hair if you’re deficient in this vitamin.  But there’s disagreement over whether biotin applied to the skin or scalp will do anything to promote scalp and hair health.  Many sources indicate that biotin is helpful to the hair and scalp only if taken internally.  However, this article in the Journal of Nutritional Science and Vitaminology suggests that biotin can indeed enter the system through the skin and improve hair and scalp condition.

Black seed oil (see Nigella sativa)

Bramhi (see Bacopa monnieri)

Burdock (see Arctium lappa)

 

Caffeine

Caffeine is a drug naturally found in plants such as tea, coffee, and cocoa.  In addition to its stimulant properties, it is a powerful antioxidant and is believed to counteract DHT, a hormone that can contribute to baldness, when applied to the scalp.

Lemon juice is acidic, so it can bleach.  Some people desire this effect and use lemon juice to bring out highlights in their hair.  If you’d rather not lighten your hair, avoid leaving lemon juice on it for more than a brief time.  The lighter your natural color, the greater the effect will be.

If using lemon around the face or eyes, try diluting it or mixing it with other ingredients to reduce the acidity.  Use lemon juice with great caution to avoid getting it in your eyes.

Clary sage (See Salvia scaria

Cocos nucifera (coconut)

Coconut oil is a staple in plant-based hair and scalp care.  It has properties that provide many benefits.  Coconut oil contains potassium, iron, vitamins E and K, and antioxidants.  Coconut oil’s lauric acid, with its low molecular weight, allows deep penetration into the hair shaft.  Fatty acids control dandruff.  The oil locks in moisture and smoothes and adds shine to hair.

Cortex

The cortex is the layer of a hair that is found between the outer layer (cuticle) and the core (medulla).  The cortex is composed of keratin molecules.  Most of the pigment of a hair is in the cortex.

Crataegus laevigata (midland hawthorn)

The Crataegus laevigata is a small to medium sized tree that produces berries. In traditional medicine, hawthorn berries are used to promote hair growth.  They contain procyanidins which have very high anti-oxidant activity and which may stabilize collagen and maintain elastin.

Fenugreek (see Trigonella foenum graecum)

Flavonoids

Flavonoids are natural substances found in plants, including most of the fruits, vegetables, herbs, juices, teas, and wines we consume.  Flavonoids (along with carotenoids) give color to these foods.  Flavonoids act as powerful antioxidants in the body.

They can improve the condition of the skin when taken internally, but they are extensively modified through first-pass metabolism as the digestive system processes the flavonoids before they reach the skin.  Flavonoids can also be applied topically as ingredients in lotions, oils, packs, serums, and so on.  Some of the more common flavonoids you may see in a list of ingredients are quercetin, catechins, anthocyanidins, and kaempferol.

Flavonoids are thought to protect the skin from UVB sunlight, counteract inflammation caused by UV radiation, and support wound healing and blood vessel health.  All of these actions promote a good environment for skin and hair health.  As such, they may help grow eyebrows back or grow eyebrows thicker.
