Your scalp is like your own little hair factory: If it's damaged, your hair may have trouble growing or may stop growing completely. So if you have sensitive scalp, think about your options before you slather on the hair dye. After all, it's better to play with temporary color or fun hair extensions than color your hair and deal with the consequences for years to come.
Permanent dye uses chemicals to break down the hair shaft and infuse the strands with color. Because it requires harsh chemicals, permanent dye isn't the best choice for sensitive skin. Semi-permanent and temporary color are better options for you, as they merely coat the hair with color. On the down side, these types wash out after several shampoos so you'll have to reapply them often.
Organic dyes may seem like the obvious alternative to coating your hair with ammonia and peroxide, but you may be surprised to learn that some organic dyes use harmful chemicals. Look for organic products that are certified, meaning they must contain mostly organic content. Regardless of the hair dye you choose, always do a strand test on a hidden section of hair to make sure your scalp doesn't have a reaction. Even all-natural products can cause rashes on some people, so be careful.
If you've never dyed your hair yourself, it's safer to have a stylist do it. The problem with home hair coloring isn't the quality of the dye, but rather that ladies are tempted to leave the dye on way longer than it needs to soak in. The results? Irritation and even hair loss. On the other hand, according to the "Vitality" magazine article "Gorgeous Hair," paying more for a salon visit doesn't mean your dye job will be "healthier." Both salon coloring and home kits use the same chemicals, so you're dealing with the same risks either way.
If you're dealing with a rash or other irritation after using hair color, see a dermatologist right away. A doctor can give you medicated hair products or other prescriptions to help out your scalp and keep you from suffering long-term damage. Also, don't use hair dye on your eyebrows or eyelashes; the skin is especially sensitive in these areas. Instead, use mascara and dust a makeup color of your choice over your eyebrows with a brow brush for a new tint.
