There are so many prohibited things to do while you are pregnant. You need to avoid specific food, medicine, and even materials. Unfortunately, I have very curly and frizzy hair, so I used to do keratin straightening for a long time. Now I can't do it. It is well known that keratin is made of the toxic combination. Keratin serums can be absorbed through the scalp and pass along to the growing baby. It is a high risk. Fortunately, there are some healthier alternatives to keratin straightening, and I examined some of them: - Professional Blowout - it is an excellent replacement for a keratin straightening. You can do it without the risk of chemical exposure. Be sure to go to a salon with a good reputation, which uses natural products. After the procedure of keratin straightening, my hair became smooth, obedient and healthy. The dyed hair after the procedure holds the colour longer as well. So I can advise it everyone, even non-pregnant women. -Hair straightening brush - a convenient, not very expensive device, which helps to straighten hair quickly and safely. The device does not spoil the hair like a flat iron, it saves time and does not require special skills. It is relevant for young mothers and pregnant ladies, as it helps to make styling and achieve the effect of smooth hair in a short time. I`m glad that I found such a device here: https://mystraightener.com/ Hope this article is useful for you:) Take care of yourself and your baby!
