By blocking these receptors or also known as the androgen receptors, the cancer cells are hindered from further progression thus, making the cancer cells incapable of enlarging and multiplying.

    Amino Acid

    Amino acids function essentially in the human body. Amino acids play a major role as building blocks of proteins and increase fat metabolism. There are over 20 kinds of amino acids from proteins, lengthy chains of amino acids unite in order to shape up to 55,000 different proteins and each protein is utilized to produce the enzymes, neurotransmitters, and hormones that sustain natural growth and as well support the adequate functions of all organs of the human body including the brain, kidneys, heart, liver and sex organs.

    Asymmetrical Hair Loss

    Asymmetrical hair loss is somehow similar to male pattern baldness. Most men endure some extent of asymmetrical hair loss in their lifetime.

    Catagen

    Catagen stage is then the gland stops and decreases the release of sebum.

    The cortex layer of the hair shaft is the cuticle. The cuticle serves as a protection to the cortex and this is seen as a colorless and thin layer. There are pigment cells that are distributed throughout the cortex and medulla giving the hair its distinctive color.

    Club Hair

    Club hair is assembled when the catagen phase occurs. It is when the portion of the hair follicle in contact with the lower part of the hair becomes attached to the hair shaft. This entire process cuts the hair off from its blood supply and from the cells that produce new hair.

    Cyproterone Acetate

    Cyproterone acetate is a type of hormone therapy drug which is also commonly known as an anti androgen.

This therapy can eventually shrink and delay the cancer.

    Dermal papilla

    The dermal papilla is situated at the base of hair follicle. The dermal papilla contains nerves and blood vessels which supply glucose for energy and amino acids to make keratin. Glucose is provided by the cells of the dermal papilla to the hair follicle, this process is essentially needed for the production of amino acids and energy accumulation. This sustenance permits the body to produce new hair.

This drug specifically inhibits type II 5-alpha reductase, the enzyme that converts the hormone testosterone to a very potent androgen hormone dihydrotestosterone (DHT)

    Follicle

    A follicle is a sac from which a single hair grows and into which the sebaceous (oil) glands open.  There are hair follicles all over the skin of the human body.

    Saw Palmetto

    Saw Palmetto works as an active antiandrogen which is seemingly similar of how a finasteride targets DHT in the body and in the scalp. Saw palmetto alleviates DHT level in our body by preventing 5 alpha-reductase thus, reducing the development of DHT, which causes hair loss.
