Does your hair get tangled or matted from teasing and hair spray? Try the Tangle Teezer, a de-tangling hairbrush that glides through wet or dry hair without tugging or breaking fragile strands. A friend brought one back for me from London, and I’m hooked. It’s not glamorous looking (it looks like a plastic horse brush), but it really works, even on matted extensions (about $16 at tangleteezer.com).

                                                                 


Does your hair hang limply?It might be time for a trim. Ask your stylist for shorter layers, which will give you more volume than long layers. If you have thick hair, it might need to be thinned out, so your stylist may use either thinning shears or scissors, in a technique called channeling.

Does your hair look dull and dry? Long hair, especially if it’s processed, can easily break, split, and lose its color. To keep it healthy and shiny, and to preserve color, try washing and blow-drying it two to three times a week instead of every day. To restore smoothness and shine, use a deep conditioner or hair mask once or twice a week, like Garnier Fructis Triple Nutrition 3-Minute Undo Dryness Reversal Treatment with olive, avocado, and shea oils (about $6 at drugstores).
