Is a Keratin Treatment Safe During Pregnancy or While Nursing?

Many women wonder whether keratin hair treatments are safe during pregnancy or while breastfeeding. The short answer is: it's best to avoid professional keratin treatments during these sensitive periods. While some formulas are labeled as “non-toxic,” the full safety profile depends on the ingredients, application method, and overall exposure.

Why Experts Advise Caution

• Most keratin treatments involve heat-activated ingredients that can release formaldehyde or formaldehyde-releasing compounds.
• Formaldehyde exposure is linked to respiratory irritation and other health risks, especially in poorly ventilated spaces.
• Pregnancy and nursing increase hormonal sensitivity, making adverse reactions more likely.
• Medical sources like Healthline and the Cleveland Clinic recommend avoiding such treatments during pregnancy and while breastfeeding.

What Medical Sources Say

Healthline advises against keratin treatments due to the potential release of formaldehyde and its associated risks.

KeratinWorks notes that even with non-toxic formulations, it’s best to wait until after pregnancy and breastfeeding due to hormonal unpredictability and possible exposure.

Everyday Health also echoes medical concerns, encouraging women to postpone smoothing treatments for safety.

Are “Formaldehyde-Free” Keratin Treatments Safe?

Even products marketed as "formaldehyde-free" may contain ingredients like methylene glycol or other aldehydes that release formaldehyde when heated. Always read labels carefully and consult a healthcare provider if unsure.

When to Consider Delaying Treatment

• During pregnancy — especially the first trimester, when fetal development is most sensitive.
• While breastfeeding — to avoid unnecessary exposure to any airborne chemicals.
• Until after nursing ends — as a precaution for both you and your baby’s health.

Safe Alternatives to Keratin Treatments

• Use keratin-infused shampoos and masks — no heat or fumes involved.
• Deep conditioning with natural oils or protein-rich treatments.
• Styling with a blow dryer and heat protectant, rather than chemical smoothing.
• Consider haircuts or styles that reduce frizz naturally.
