What are the precautions for the use of foam hair dye

Hair dye is the most common hair beauty product. Many people now buy and use hair dye themselves and dye their hair by themselves. Therefore, foam hair dye is more and more favored by consumers.

So can foaming hair dye damage your hair? What should be paid special attention to when using it? Any hair coloring product can cause damage to the hair and scalp, but in varying degrees. Compared with hair dyes, foam hair dyes are relatively less harmful, because foam hair dyes are semi-permanent, and use small molecule fuels to penetrate into the hair to achieve hair dyeing effects. The effect is fast and short-lived, with less damage to the hair and scalp.

At the same time, general foam hair dyes will add some softeners to make the hair look smooth after dyeing and reduce dry ends, but with the continuous washing of shampoo, this smooth effect will be lost, and the hair will still have the problem of dryness . If you're using foam hair dye for the first time, you'll need to do an allergy test according to the package directions. If you have a history of allergies, use a cotton pad to dip a little neutralizer and hair dye in advance, and stick it on the inside of your wrist for more than half an hour.

If you get redness and itching, it means it's not suitable for use; if you have cuts or eczema on your scalp or face, be sure to avoid using hair dye until recovery. To minimize damage to your hair and scalp, avoid perms, bakes, and other treatments before using foaming hair dye. Not to mention washing your hair a day or two in advance, leaving an oily protective film on the scalp.

If you need to wash your hair on the same day, don't use conditioner, it will affect the color level. After dyeing your hair, try to choose a low-alkaline shampoo and use a solid conditioner for maintenance to maintain long-lasting hair color and soft hair. You can toast the oil every other month to nourish your hair and reduce dryness and split ends.

Avoid high heat or use strong cleansing shampoos, as this will not help the color persist. Avoid secondary hair dyeing or perm in a short period of time, because it will cause great damage to the hair and scalp, dryness, hair loss and other problems, you can perform secondary processing more than once every six months. In general, using foaming hair dye is still harmful, but it will be less harmful than other hair dyes.

Before and after use, we should understand whether it is suitable for use and maintenance skills to obtain more satisfactory results.
