Dyeing hair while breastfeeding: how long after delivery is safe?

Many women do some kind of chemical on their hair. At the stage of pregnancy, a series of care needs to be taken, but what about after delivery? Can you already make your hair highlights or dye your hair?

The Healthy Minute clarifies some fundamental precautions to protect the health of the mother and baby:


Can you dye your hair while breastfeeding?

Yes. Currently, the tinctures available on the market have several formulations that are not considered toxic to the organism, even to lactating mothers.

Although there is little research that shows the effects of dye during breastfeeding, dyeing hair poses no risk to the baby.

According to information from the Brazilian Society of Pediatrics (SBP), women do not need to stop dyeing their hair while breastfeeding.

What is known is that the quality tinctures that are used by mothers do not pose a great threat to the child who feeds on breast milk.

SBP experts reinforce that if the dye has no lead in its composition, coloring the hair is considered safe for both mothers and babies. It is known that lead is a metal that can be passed on to the child through breast milk.

Another important issue is that the smell of hair dyes and / or cosmetic procedures can be harmful for children. Some pediatricians believe that, depending on the product used, it can cause allergic rhinitis, that is, inflammation of the mucous membranes of the nose or different types of irritations in babies.

Therefore, in case of doubts as to whether these substances are harmful to the baby, it is important to consult a pediatrician or obstetrician to have correct guidelines before any aesthetic procedure.

What are the precautions when coloring my hair while I am breastfeeding?

The main care that mothers who are breastfeeding should take is in relation to the composition of the chosen dye. This product needs to be free of heavy metals like lead, as it can cause problems in the child’s development, even in small quantities.

Therefore, when dyeing your hair it is important to invest in quality products without this metal. The labels of hair dyes that contain lead in their composition need to bring this information and warn about the risks of use in specific groups of people, such as lactating women. Therefore, always read the labels of these products before using.

If you find it necessary, buy the dye and take it to the hairdresser or hairdresser to be sure what is being applied to the hair.

An alternative is to use semipermanent dye (also known as toners) that are free of these components. However, the disadvantage is that they last less and may fade during washing. But it is a way to ensure safety and keep the hair toned for a while.

It is also important to avoid taking the child to the beauty salon while dyeing their hair so that they are not exposed to the products. And if you are going to do it at home, avoid that it is close to the dye.

Can lactating women make lights?

Yes. The lights are very thin strands in lighter shades of the strands that are pulled from the root to the tip of the hair.

The only caveat for nursing mothers in these cases is that the tincture or bleach does not touch the scalp. The strands need to be pulled at least one finger apart from the root of the hair so as not to be scratched.

This attitude can prevent the substances used in the tincture or bleach from coming into contact with the bloodstream and passing it to the baby during breastfeeding.

Can you use paint with ammonia?

Yes. According to the Brazilian Society of Pediatrics (SBP), tinctures that contain ammonia in their composition also do not need to be avoided by those who breastfeed.

That’s because there is still no scientific evidence to show that these products can harm babies who are being breastfed by mothers.

But, in any case, if possible, it is better to avoid the substance during the lactation phase and choose more natural options such as toners.

Can you do other hair chemicals?

It depends. There are several types of hair treatments available today. And some products can be harmful to lactating mothers.

This is the case with progressive brushes that use formaldehyde and other procedures that may contain harmful substances for both the baby and the mother.

Formaldehyde is one of them, which serves as a straightener in these products and has not been approved for use by the National Health Surveillance Agency (Anvisa) or the World Health Organization (WHO) due to its high potential for poisoning the organism.

Therefore, its irregular use can cause irritation, itching, swelling, burns, burning eyes, cough , shortness of breath, among other more serious symptoms.

In these cases, when the mother uses some chemical that contains formaldehyde, there is a risk that the substance will be absorbed through the skin and transmitted through milk to the child.

In addition to formaldehyde, it is important to stay away from substances such as methylene glycol, glyoxylic acid, formic aldehyde, oxymethylene, oxymethane and lead.

Thus, it is essential to check the chemical composition in the product packaging before using it.

In addition to the progressive, there are other hair procedures that can take chemicals such as relaxation, sealing, capillary botox , chocolate or sugar brush, keratinization or cauterization.

The recommendation is to check the packaging and even discuss with health experts to find out what the risks are for all components and if there is clearance to do the procedures. He / she must guide what the necessary care is.

It is also important to have a lot of confidence in the chosen beauty professional and to know that the products used in hair treatments are quality and do not pose any health risks. There are many products that are not registered by Anvisa and can cause problems when used.

How long after delivery can you dye your hair?

There is no consensus on the exact period. Ideally, aesthetic procedures such as dyeing hair should be performed after the puerperium , a period just after delivery that usually lasts 6 to 8 weeks. The puerperium comes to an end when the woman menstruates again.

But the ideal is to wait a few months after delivery, if it is possible to wait. It is worth emphasizing that any chemical or aesthetic procedure should not be performed without the authorization of health professionals who accompany the mother and baby.

It is even more worrying if the mother has an allergic history to any component used in hair dyes.

Normal and cesarean delivery: is there a difference in time?

There is no difference in the period to be expected to dye your hair due to the type of delivery.

What can happen is that in childbirth performed through a cesarean section, the mother needs more time to recover due to the abdominal cut. But this is quite individual.

Anyway, the ideal is that aesthetic procedures like dyeing the hair are done after the puerperium, regardless of the type of delivery performed.
