In order for Caffeine to help stimulate hair growth, there must be enough caffeine applied to the hair follicles and it must remain in contact with the skin surrounding the hairs for about an hour.

The majority of shampoos containing caffeine ​do not contain enough caffeine to be effective.

And the shampooing habits of most people are such that they do not stay in the shower for an hour with the shampoo in their hair. Most people leave it on for about 1 minute...not 1 hour.

So using caffeinated shampoo is probably not going to work.

On the other hand, essential oils combined into a hair oil treatment that are infused with enough caffeine to be effective can be easily applied to the scalp and left on for an hour.

After doing a caffeine hair oil​ treatment for an hour, you can take a shower and rinse out the oil with any shampoo. This procedure will give far superior results than using a caffeinated shampoo for a minute or two.

Healthy hair and regular hair growth relies on a number of factors, including vitamins, minerals, and the presence of other nutrients. Medications, genetics, nutritional deficiencies, and underlying diseases and disorders can all negatively affect your hair. Caffeine, a naturally-occurring compound found in several plants, might have a beneficial effect on your hair follicles to promote healthy hair.

The National Institutes of Health published a study proving that caffeine stimulates hair growth in both men and women. Click Here to read more about the study.

Cycles of Hair Growth

The condition of your hair, as well as your hair length, is determined by the health of your follicles and your hair growth cycle. Each hair follicle contains a population of progenitor cells, capable of assembling hair shaft tissue, to ultimately support hair growth. During the initiation phase of hair growth, the cells begin to manufacture a new hair shaft, which continues to grow throughout the elongation phase of the hair cycle. After a predetermined period of hair growth--which can range from days to years, depending on the type of hair follicle--the hair remains static within the follicle, then eventually falls out. Defects in the initiation, elongation or shedding phase of hair growth can all lead to hair disorders.

Caffeine and the Hair Cycle

Caffeine has the ability to interact with your hair follicles, helping to guide your follicles' behavior and regulate hair growth. A study published in the "International Journal of Dermatology" in 2007 found that the presence of caffeine stimulated laboratory-cultured hair follicles, increasing hair growth. As a result, caffeine might help to restore hair growth, or prevent abnormal hair loss. However, the clinical effects of caffeine on promoting hair growth have not yet been thoroughly investigated.

Caffeine Absorption for Hair Growth

There are several ways to expose your hair follicles to caffeine, to potentially stimulate hair growth. Caffeine consumed via food and beverages enters your bloodstream, and eventually reaches your hair follicles. In addition, your hair follicles can absorb caffeine directly via topical application of caffeine-enriched shampoo, according to a study published in "Skin Pharmacology and Physiology" in 2007. This might allow doctors to expose your hair follicles to a high dose of caffeine, without causing the side effects that can occur due to high-dose caffeine ingestion. As a result, hair products containing caffeine might represent treatments for hair loss, if caffeine eventually develops into a drug therapy for alopecia.

Possible Implications in Hair Loss Due to Cancer Therapy

Preliminary studies have identified caffeine as a possible treatment for hair loss, which might have implications in the treatment of other diseases. Many cancer patients receiving radiation therapy suffer hair loss, due to damage to the hair follicles by the radiation. A study published in the "Journal of Radiological Protection" in 2002 found that treating laboratory mice with caffeine helped reduce hair loss following radiation treatment. Although further research into the effect of caffeine on radiation therapy-induced hair loss in humans requires further investigation, caffeine might eventually help prevent hair loss due to some cancer therapies.

Why Use Neem Oil for Hair?

Neem is a multipurpose herb and has exceptional medicinal properties, making it a favorite for curing and healing numerous ailments. Neem oil is full of antibacterial, antifungal and anti-inflammatory properties as well as fatty acids and vitamin E. It is a great natural alternative to hair treatments filled with harmful chemicals.

Neem oil is a natural cure for all your scalp and hair problems. Neem oil is extracted from the seeds and the fruits of the neem tree, a large evergreen tree native to India and Southeast Asia. Neem oil has been used for centuries in traditional Indian medicine as a treatment for various skin and scalp conditions.

Neem oil is also used in traditional Ayurvedic remedies as an antiseptic to fight viruses and bacteria. It removes toxins from the body, purifies the blood and neutralizes damaging free radicals. It is known to be especially nourishing for the hair. The neem tree has been shown to have anti-inflammatory, anti-fungal and antibacterial properties. Every part of the tree can be used for medicinal purposes, including the leaves, fruit, seeds, bark, gum and oils. The oil has the highest amount of the substance called azadirachtin, which gives the tree its anti-fungal and pesticide properties. As a result, neem oil is a fantastic and effective treatment for many ailments related to your hair. Read on to discover the many benefits this wonderful oil has to offer!

Benefits of Neem Oil for Hair

Neem oil has countless benefits for the hair and scalp, including relief from a dry, itchy scalp and dandruff, as well as giving you silky, shiny, strong hair.

Promotes hair growth:

Neem oil is known for its ability to increase hair growth due to its high level of anti-oxidants. Neem oil protects the scalp from damage caused by free radicals. It also has regenerative properties, which help keep your scalp in good health – a necessity for healthy hair. It can be used to counter the effects of hair thinning due to stress, medication and environmental toxins. Regular application of neem oil will strengthen hair from the roots, increase blood circulation and encourage hair growth. 

Split ends:

Neem oil is known for its ability to add moisture to the hair thus helping to repair damaged cuticles. Mix a few drops of neem oil with one of your favorite carrier oils (such as coconut, jojoba, olive or almond) and apply the mixture to your hair and scalp. Leave it on your hair for a few hours, then rinse it out with a mild shampoo.

Frizzy hair:

Neem oil can be used as a conditioning agent for rough and frizzy hair. Using neem oil will help to add shine to the hair and will help to rehydrate parched strands. Add a few drops of neem oil to your shampoo, apply to your hair and leave on for 3-5 minutes. Once hair is rinsed and dried, it will appear shinier and healthier.

Premature graying of the hair:

Regular application of neem oil can reduce overall graying of the hair, while also helping to relieve skin infections. If your hair is going gray as a result of hormonal imbalances or other hair problems, then neem oil may be able to help. However, neem oil will not be able to reverse hair that is going gray due to age.

Healthy scalp:

Excess sebum (oil) production can cause thinning hair and hair loss by clogging the pores of the scalp. This can also cause inflammation of the scalp, leading to damage of your roots. Neem oil helps to treat these conditions by cleansing the scalp and stimulating blood flow to the skin. It also helps to nourish the scalp and the roots of your hair. Because of its anti-inflammatory and anti-fungal properties, neem oil can help to improve the condition of your scalp. Neem oil also contains a high concentration of fatty acids, which also help to nourish the scalp.

Healthy hair:

When applied on a regular basis, neem oil can result in healthier hair as it is rich in nourishing essential fatty acids and antioxidants for protection and prevention of damage. 

Dandruff:

Neem oil is a natural cure for dandruff and dry scalp. It is effective against several human fungi including candida, which is known as a major cause of dandruff. Many dandruff shampoos contain neem oil. Regular use of the oil can prevent dandruff from forming as it helps to maintain scalp health and PH level.

Head lice:

Neem oil can be used as a safe and natural alternative to get rid of head lice. (We recommend LiceKiller Brand which contains Neem Oil and other lice killing oils.) Neem oil contains azadirachtin, an insecticidal ingredient, which disrupts the growth and reproduction of lice. The pungent odor of neem oil is strongly disliked by lice, and will keep them from crawling onto your head and hair, thus working as a preventative treatment. Leaving the neem oil on the hair overnight will help to kill off any lice. The lice can then be removed in the morning using a nit comb. Repeat this treatment five to six times, on alternate days, using neem oil until lice have disappeared.

Eczema:

Eczema is a skin condition characterized by a dry, red, itchy, flaking skin and scalp. The anti-inflammatory substances in neem oil act similar to non-steroidal drugs and help to reduce the redness and irritation caused by eczema. Neem oil is rich in fatty acids and glycerides that easily penetrate the outer layers of the skin thus helping to restore the protective barrier and helping to prevent moisture loss. Neem is also a strong analgesic (pain killer) and will bring relief from the discomfort of dry, itchy skin.

Dry, undernourished skin:

Because of the fatty acids in neem oil, it can be used a conditioning treatment for both scalp and hair. Its moisturizing effects revitalize and restore dry, undernourished or rough hair, bringing hair back to a smooth and silky texture.
