Dry
By now, you've learned that curly hair is prone to dehydration. A perpetually open cuticle is a magnet for moisture-sappers such as harsh cleansers, heat styling and environmental forces like wind and sun. A dry mane acts "tense"— strands don't relax and fall into healthy curl patterns. If you spend lots of time outside or are addicted to heat styling, weekly or bi-weekly deep conditioning treatments are vital to maintaining a beautiful set of curls.
Brittle
Your tresses are most likely fragile from repeated permanent hair coloring, straightening chemicals and excessive styling product buildup. Just as you cleanse your face of makeup and dirt to prevent clogged pores, you must rid the hair of outside elements, such as silicones, waxes and oils that may stifle the hair shaft. Styling is a real challenge with brittle hair because it doesn't want to fall into a shape— it behaves lifelessly despite careful blowdrying or use of a curling iron. Give your hair a vacation from any chemical processes and treat it to weekly conditioning treatments to restore its lost moisture and nutrients and rebuild its strength. Fortunately, this level of damage is rare.
Split Ends
Every mane curly, straight, short, long is susceptible to split ends. Strands become dry and "empty" from a variety of assaults, including the environment, frequent heat styling, and harsh cleansers. In this condition, the cuticle remains open and feathery. These tiny raised layers are actually split ends, also called flyaways. They are weightless and lift away from the cuticle creating that halo of frizz. Contrary to popular belief, split ends are found all over the hair and CANNOT be fixed with cutting. The best treatment for split ends is to feed your hair, just like your skin. A nourished hair shaft will have enough internal weight to keep the cuticle closed so that each curl is smooth. Clearly, trimming split ends is not an option— you might as well shave your head. Split ends can appear anywhere so frequent deep conditioning is the only way to prevent them. Note: You'll see the most flyaways in the winter when the hair is prone to extreme dryness. For a quick fix, spray tresses with a leave-in conditioner to quench your manes thirst.
