Permanent hair for color breaks down the hair cuticle and deposits pigment into the hair shaft. Unlike semi-permanent color for hair, permanent hair color can be used to lighten your hair. It accomplishes this by bleaching hair and depositing color in a one-step process. Permanent color for hair is more effective for covering gray hair. Although the color will fade over time, it can't be washed out or removed to return to your natural shade. Permanent hair color can be damaging to hair, and long-term use can result in permanent, irreversible harm to your hair. Long-term damage that results from the use of permanent color for hair can be minimized by being extra careful with your daily hair care regimen.
Hair highlights, streaking, weaving and foiling
Hair highlights can be added to the hair by any of the above methods. Any hair can be highlighted and the hair is usually given more depth and texture by this process. You can add lighter, brighter strands of hair overall or just create a few highlights in specific areas. This is a great process for the timid or first time blondes. I should also mention "hair low lights" here. The same basic processes are used in both color treatments. However, instead of lightening the hair, creating low lights involves adding darker shades of blonde highlights or warmer brown hair color highlights. Hair highlights have come a long way in recent years and a talented hair colorist can weave two or three different natural looking highlights and lowlights into your hair, creating beautiful effects.
