• DRY HAIR - do you feel like your hair is too brittle on the ends? You may need a hair cut.
  Is it dry all over the hair shaft? Maybe your hair is over processed chemically - try to do only one chemical process, either color or perm. Have it done professionally. If you are doing it home you may be destroying your hair by using a wrong product or you may be applying it wrongly. Maybe you need to give your hair a break from all that chemical processing.
  You are telling me you do not color or perm your hair and it is still dry? Maybe your hair is coarse and dry naturally? Shampoo it 2-3 times weekly, use moisturizing conditioners and never use any products containing mineral oil, lanolin etc. These products will block your oil glands, that give your hair the best - natural lubricant. On top of that the oily substances will attract dirt and make your hair looking dull.
  Are you drying your hair properly? You should gently squeeze the hair with your towel, never rub it, especially never rub it hard. If you do, you are destroying the protective hair cuticle, making it look dry and without any luster.
  Are you an avid swimmer? Do you spend a lot of time in the sun? Protect your hair with swimming caps and hats, use sun block products.
  Do you walk out of your house or appartment into the freezing air with your wet hair? Don't do it. Water inside the hair shaft freezes, expands and rips the hair. All you have is damaged hair.

• OILY HAIR - Your oil glands produce generically and hormonally a lot of oil and your hair cannot absorb so much of it. You should not shampoo your hair with hot water, and never use a hair dryer on the hot air setting. Both of these stimulate your oil glands to release even more body oil. Use only lukewarm water and give yourself cold rinses as well. Use shampoos designed for oily hair . You can also have your hair colored, or permed as your hair cuticle will get "opened" (or lifted) and therefor hair will absorb more of the oil.

• STYLING THE STRAIGHT HAIR THE FAST WAY  - after your hair has been shampooed and hair conditioned, towel dry your hair, then quickly blow dry the hair till it's completely dry. Take the biggest Velcro rollers for long hair (smaller size for shorter hair) and insert them in sections. You don't have to make perfect sections, but you should use the rollers just like the comb to smooth the hair just a bit, so it doesn't get wrinkled, then roll them in. This way hair gets plenty of fullness. Hair spray after you insert all your rollers in. Go get dressed, make your coffee, eat breakfast, put your make-up on etc. Take the rollers the very last minute before you leave the house for work. Don't forget to brush your hair (or just quickly blow dry your root area only - to break any separations from rollers), give yourself last mist of spray and voilà, you look great.
• HAIR PART that is always in the same spot, can contribute to the "flatness" of your style. You can use the popular zigzag parting, that is never in an exactly same spot, or alternate parting on each side

STYLING THE CURLY HAIR - after shampooing the hair, towel dry it and work a dab of hair conditioner into the hair. Comb it with a wide tooth comb, add your favorite Styling Gel and crunch and crunch and crunch, while blow drying your hair with a diffuser (your head up side down to add an extra fulness). The diffuser is a wonderful invention. It slows down the air flow, but retains the heat. Hair doesn't get blown away and doesn't get frizzy, yet it gets dry. I get very nice firm cork screw like locks. If your hair still has some frizzes on the ends (especially before the hair cut) put a little dab of gel in your palms, rub them together a "crunch" it into your hair

  COWLICKS - does your hair stands up after your haircut? Your hairdresser is probably cutting your hair too short in that area. Tell your stylist about the problem ahead of time as he/she needs to pay special attention to these areas. I usually cut the cowlick very short in the nape area and leave it long on top (the length of the hair will keep the cowlick down). Another tip on keeping it down is wetting the hair and combing it in the direction of the growth, never against.
