Professional shampoos and conditioners are sold in salons and spas. The most important thing to consider when selecting professional shampoo and conditioner is hair type, whether it is dry or damaged, fine or thinning or color-treated.

As your follicles stop producing melanin -- a process ruled by your genes more than your lifestyle -- your hair pigment fades and you go gray. While the graying process is simple, the acceptance process often comes with a few complications.

Hair can consist of different varieties from long and short to thick and thin. If you have fine or thin hair, you may want to thicken it a bit for more style. Fortunately, for those who want thicker, fuller hair, there are products on the market which are designed to help you achieve your goals.

If you have a simple haircut, you may be able to trim your own hair between salon visits, which will save you time and money. Simple haircuts include one-length cuts and long layers, a style in which all of the hair is combed upward to the same location and bluntly cut.

Minoxidil is the active ingredient in heavily advertised hair restoration medications like Rogaine and Hairgro. It's typically used to treat thinning hair and baldness on the scalp, but the American Academy of Dermatology points out that it can also be used to restore eyebrow hair.

Perms or chemical relaxers have an extremely damaging effect on hair when used incorrectly. Because breaking and dryness often plague permed black hair, limit the number of times per year you relax your hair to four or five, says Susan Taylor -- a board-certified and Harvard-trained dermatologist.

Hair on your belly is unsightly in a swimsuit, but if you've tried to shave it off, you know it can come back coarse and dark. Although hair growing back thicker generally is a myth, the American Academy of Family Physicians notes that stubble, the blunt edges of hair that has been shaved off, will show up.

Hair is often straightened with a flat iron -- which applies direct dry heat to the hair -- or with chemicals in a salon. Although these processes can make hair look smooth and shiny temporarily, over time they strip hair of lipids and oils, removing proteins and drying out the cuticle, the outer layer of the hair.

While having facial hair is normal for a man, it can be unsettling when anything more than peach fuzz shows up on a woman. Unwanted facial hair is called hirsutism, which results in excess hair on the face and body and tends to predominantly affect women.

The excessive use of chemical treatments often results in over-processed hair and hair breakage.

Fine hair tangles easily when worn long. These tangles can cause hair breakage and be painful to remove when brushing and styling your hair. Wind, sleeping and sports activities all contribute to fine hair tangles, and it often seems impossible to prevent this from happening.

Hot oil treatments can be a great way to add moisture to relaxed or damaged hair. If you are African-American and your hair has been relaxed with a chemical treatment, you may want to consider using a hot oil product to add extra moisture and shine to your hair.
