Semi permanent hair color works by depositing pigments along the outside of the hair shaft known as the cuticle. The color does not penetrate the shaft or chemically alter the hair strands. Results from semi permanent dyes typically remain vibrant for 6 to 12 washes, and you can help to extend the results for as long as possible by using shampoos and conditioners designed for color-treated hair.
Because semi permanent hair color usually is free of ammonia and low in hydrogen peroxide, it does not dry out the tresses in the way that permanent hair dye can. Semi permanent formulas are excellent for first-time users or for testing out a completely new hair color. They can also be used in place of permanent dye to give hair a break from harsher chemicals. Formulas that contain semi permanent color can be used to cover gray and darken the hair; however, they usually cannot lighten locks due to the reduced amount of peroxide.
Many semi permanent hair color products are specially formulated to keep the hair hydrated. Some formulas have a creamy base that contains emollients to replace lost moisture in the strands. Others have a separate oil treatment or deep conditioner that is applied after coloring to rehydrate the tresses.
Some semi permanent hair color solutions are made entirely from natural ingredients, such as henna. These products can be very beneficial for men and women with sensitive skin, as the natural formulas are less likely to cause irritation along the scalp and hairline. Natural formulas are also very gentle on the strands, so they are ideal for hair that is dry or damaged due to the use of permanent hair color, heat from styling tools or the effects of the sun.
A small number of semi permanent hair color formulas are designed to enhance the bleaching effects of the sun to lighten the tresses. These are single-step products that are sprayed right onto the strands prior to sun exposure. The results from the formulas are usually subtle and look very natural.
Some semi permanent hair coloring products are made especially for men. They come in a limited number of natural hues and are primarily used for covering grey. These products often have simpler methods of use and may only require one step to produce results.
When comparing semi permanent hair color options, take into consideration both the ingredients that their formulas contain and their colors. To ensure best results, read the product packaging carefully and follow the instructions closely. You should also conduct a strand test before applying the color to your entire scalp.
