ALPHABETICAL ORDER

• 6BAP (6-Benzylaminopurine)
    
• About hair loss - technical and comprehensive discussion about hair loss, hair structure, hair biology, and hair regrowth. Click here.
    
• Acetamide
  • Acetamide is usually used as a solvent for chemicals. This compound is used in a lot of the hair loss topical lotions or shampoo.

• Acid polysaccharides
    
• Aldactone (spironolactone) - a potent anti-androgen commonly prescribed for women and sometimes men with androgenetic hair loss. Can be taken orally or used as a topical agent. Click here for more spironolactone information.
   
• Alopecia
  • This is a medical term for hair loss or baldness in general. There are different types of alopecia. 

• Alopecia androgenetica
  • This is a medical term for male pattern baldness or female pattern baldness. This type of hair loss is usually hormone related.

• Alopecia areata

  • It refers to the condition when there are well defined oval shape bald patches on the scalp.

• Alopecia totalis
  • It refers to the condition when all the hair on the scalp is lost.

• Alopecia universalis
  • This is an extreme case of baldness where all the hair on the scalp and the entire body is lost.

• Amino acid
  • Amino acids are the building blocks of proteins and are the end products of protein digestion. They are essential for human metabolism.
  • There are almost 100 kinds of amino acids. The main source of essential amino acids is from food. Essential amino acids include: methionine, cysteine, histidine, isoleucine, leucine, lysine, tyrosine, threonine, valine, phenylalanine and tryptophan.
  • Some proteins contain all the essential amino acids, eg: milk, cheese, eggs and meat.
  • Once the protein is broken down by means of digestion, amino acids pass onto the bloodstream and is absorbed by the tissue depending on the tissue's requirement for amino acids.
  • Since protein is the building block for healthy hair, lack of amino acids in the body may adversely affect hair growth.

• Anagen
  • It refers to the growing phase of hair cycles.

• Anti-androgens - Antiandrogens are sometimes referred to as androgen antagonist. It represents a family or a class of hormone antagonist compounds that are capable of preventing or inhibiting the biologic effects of the male sex hormones (androgens) on androgen-responsive or androgen-sensitive tissues in the body. The word antiandrogen is sometimes used synomously with the term "androgen receptors blocker" because antiandrogens usually work by blocking the appropriate receptors, competing for binding sites on the cell's surface, literally obstructing the androgens' pathway. Also read article on Anti-androgens contributed by Dr. Proctor. 
  • To remove the effects of androgens:
    1. Anti-androgen: binds the androgen recptor which inhibits its action
    2. 5-alpha-reductase inhibitors: less DHT means less potent androgens
    3. Androgen receptor(AR) downregulation: Less AR, obviously, means there is less for the androgens to bind to and less signaling. This can be done in many ways most of which are not well understood. Inhibition of GSK-3beta is one way of doing lowering the amount of AR that has been confirmed.
