Using vitamins as part of a natural approach to treating hair loss can be a healthier method to use as long as you are informed about what you are using.

In large doses, even many types of vitamins or natural supplements can be harmful or even fatal.

However if used correctly, methods using vitamin A for hair loss treatments may be healthier than those containing chemicals. These chemicals may lead to side effects. Being informed of more natural options is a way to avoid taking treatments with chemicals.

Vitamin A

Vitamin A describes a group of five similar compounds. The most popular members of the vitamin group are retinol and beta carotene. Others are carotenoid compounds.

Vitamin A occurs as retinol in animals. Actually, it is found as its ester, retinol palmitate.

It is a yellow, fat-soluble compound which is converted to retinol in the intestine before storage. The stored retinol is then converted to retinal, a compound that absorbs light and is essential in the eyes for color vision and seeing in low light.

The other Vitamin A compounds including beta carotene, alpha carotene, gamma carotene and beta cryptoxanthin are derived from plants. They are converted to retinal in omnivores and herbivores but not in carnivores.

Retinol is the most potent form of Vitamin A, therefore, plants are not recommended to serve as the sole source of the vitamin.

In fact, Vitamin A supplements and foods fortified in Vitamin A provide more of the vitamin than most plant-based sources.

The recommended daily intake values of Vitamin A vary with age. Children need between 300 and 500 micrograms per day while adolescents and adults should take between 600 and 900 micrograms of the vitamin per day.

Pregnant mothers are advised to take 770 micrograms per day and breastfeeding mothers should ingest 1300 micrograms of Vitamin A daily.

Vitamin A is essential to quite a number of biochemical processes in the body. It is known to be central to vision through its interaction with the rods and cones of the eyes.

The vitamin is also known to the important to gene transcription and expression, a healthy immune system, development of human embryos and production of red blood cells.

Vitamin A also contributes to skin health and has antioxidant properties.

Vitamin A can be found abundantly in the following food sources: animal livers, butter, carrot, spinach, broccoli, cheese, mango, milk and egg.

There are two kinds of Vitamin A deficiency: primary and secondary. In primary Vitamin A deficiency, the individual does not ingest the recommended daily amount of the vitamin either from plant or animal sources.

Secondary deficiency occurs when certain factors including zinc deficiency, smoking and alcoholism affect the optimal absorption of the vitamin from the intestine.

Both forms of Vitamin A deficiency produce the same outcomes.

Signs of deficiency in the vitamin include impaired vision, night blindness, dryness of the mucosal membranes of the eyes, respiratory tract, and urinary bladder leading to conjunctivitis, total blindness, respiratory and urinary complications.

Vitamin A deficiency also produces an impaired immune system and the formation of white lumps in hair follicles. This later sign quickly leads to hair loss.

On the other hand, too much supplementation of Vitamin A can lead to toxicity. Since Vitamin A is a fat-soluble vitamin, it is not as easy to eliminate from the body as the water-soluble vitamins.

Acute toxicity is seen when the level of Vitamin A in the body reaches 25,000 IU per kg. This can be reached by consuming about 4,000 IU of the vitamin every day for at least 6 months. This toxicity can lead to renal failure and liver damages.

Signs of Vitamin A toxicity include nausea, anorexia, vomiting, irritability, blurry vision, headaches, body pains, lethargy and hair loss.

Just as for its deficiency, Vitamin A toxicity shares certain common signs such as dryness of the mucous membranes, poor skin health and hair loss.

Therefore, supplementation with the vitamin for the treatment of alopecia should be carefully monitored, and high doses should not be taken for long-term therapies.

Vitamin A and Hair Loss

The antioxidant properties of Vitamin A are especially useful for the protection of hair follicle cells. Circulating free radicals damage cells easily and accelerate the process of aging.

Vitamin A can mop up these reactive radicals and prevent them from damaging the cells of the hair follicles.

Similarly, Vitamin A supplementation prevents dryness of the scalp and wilting of the hair pores. This also contributes to the prevention of hair loss because a well-oiled skin signifies a well-nourished skin. In this way, hair shafts are healthier and the hair appears lush and full.

Since Vitamin A supplementation requires a fine balance in order not to worsen hair loss, the recommended dosage of the vitamin in the treatment of alopecia is usually between 5,000 and 25,000 IU per day.
