If you are expecting, you might already know that a few things are temporarily off-limits, like alcohol, certain medications, and some foods. But what about hair dye? Is coloring your hair during pregnancy something you need to put on pause?
The good news is: not necessarily. Being pregnant does not mean you have to give up your usual hair care routine. It is more about taking a few extra precautions and using a bit of common sense to keep both you and your baby safe.
Can hair dye be harmful during pregnancy?
One of the most common concerns about using hair dye while pregnant is the potential effect of the chemicals. While it is true that permanent and semi-permanent dyes contain chemical ingredients, the amount you are exposed to during typical use is very low and not considered harmful.
Your scalp absorbs only a small amount of the dye, especially if your skin is healthy and unbroken. As for the fumes, you are unlikely to inhale enough to cause harm, particularly if you are in a well-ventilated space.
If you choose to dye your hair during pregnancy, read on for safe ways to do so and some helpful tips.
Wait until the second trimester
If you regularly dye your hair, you are probably used to touch-ups every four to eight weeks. During pregnancy, hormones can make your hair grow faster than usual and even change its texture or color.
However, the first 13 weeks of pregnancy are a critical time for your baby's development, especially for the nervous system and major organs. You can learn more about this in our week-by-week pregnancy guide.
Even though only a small amount of hair dye is absorbed through the scalp, there is limited research on the safety of dye during early pregnancy. For this reason, many experts recommend waiting until the second trimester, when the potential risk is much lower.
Once you are past the first trimester, let your hairdresser know that you are pregnant so they can help you choose the safest option. If you plan to dye your hair at home, make sure to take a few extra precautions.
Always test the hair dye first
Whether you are coloring your hair at home or visiting a salon, it is important to do a patch and strand test before applying dye to your whole head. This is true even if you have used the product many times before. Pregnancy can change the way your hair and skin react to certain ingredients, so something that worked well for you in the past may cause irritation or behave differently now. Testing a small amount first can help avoid unwanted reactions or surprising results.
Coloring your own hair vs at the salon
You might wonder whether getting your hair colored at a salon is safer than doing it at home. In terms of ingredients, most salon and at-home dyes contain similar chemicals. However, some salons do offer more natural or organic options, which may appeal to those looking for gentler alternatives. That said, there is currently no conclusive research proving that salon treatments are significantly safer during pregnancy.
However, one key advantage of going to a salon is the professional application. Licensed hairdressers are trained to apply color with precision and care, which helps reduce the risk of skin irritation, uneven results, or leaving the dye on for too long. Their experience also means they are more likely to take the necessary precautions to protect your scalp and overall well-being throughout the process.
If you choose to color your hair at home, be sure to follow these precautions:
- Always dye your hair in a well-ventilated area to avoid inhaling too many fumes
- Do not leave the dye on longer than recommended in the instructions
- Wear gloves while applying the color
- Rinse your scalp thoroughly after the process is complete
- Never dye or bleach your eyebrows or eyelashes, as this can cause irritation, swelling, infection, or even pose a risk to your eyesight
Most importantly, whether you dye at home or at the salon, if you have a scalp condition like eczema or psoriasis, be extra cautious. Your skin barrier might not be as effective, which could increase the likelihood of chemicals being absorbed into your body. Avoid dyeing your hair if your scalp is irritated, sunburned, or damaged.
Safer alternatives to full hair dye
If you are still unsure about dyeing your entire head of hair while pregnant but want to maintain some upkeep, there are several alternatives that can enhance your hair without the need for full-color treatments, all while minimizing any potential risks. These include:
- Highlights or balayage: techniques like highlights or balayage involve applying dye only to certain strands of hair, without touching the scalp. This greatly reduces the chances of chemicals being absorbed through the skin.
- Semi-permanent color: you might also consider a gentler option such as a semi-permanent vegetable-based dye, like pure henna. These types of dyes typically contain fewer harsh chemicals and can be a safer option during pregnancy.
- Hair gloss: Hair gloss treatments are a great way to boost shine and smoothness. While gloss usually lasts for about eight washes, it’s a low-commitment way to maintain your hair's appearance. Gloss can often be applied without touching the scalp, reducing exposure to chemicals even further.
- Root touch-up stick or spray: If you are just looking to cover roots, a root touch-up stick or spray can do the trick. These products offer temporary coverage for grey or darker roots and wash out easily, eliminating the need for a full dye job.
Looking good and staying safe
We understand that everyone has their own reasons for wanting to maintain their hair during pregnancy. Feeling and looking your best is important, but so is prioritizing the health of your baby.
Ultimately, the decision to dye your hair during pregnancy is a personal one. If you're unsure, it’s always a good idea to consult your midwife or GP for personalized advice and guidance.
FREQUENTLY ASKED QUESTIONS
Can I dye my hair if I am breastfeeding?
While there is limited research on the topic, there is no evidence suggesting that the chemicals in hair dye can transfer into breast milk. To be on the safe side, it’s a good idea to avoid having your baby nearby when you’re dyeing your hair to prevent them from inhaling any fumes.
Is it safe to bleach your hair during pregnancy?
Bleaching your hair requires similar precautions to hair dyeing. For added peace of mind, it’s recommended to wait until after the first trimester. Be sure to bleach your hair in a well-ventilated area to minimize inhaling fumes, and always wear gloves to protect your skin. While bleach can be absorbed through the skin, it typically doesn’t reach harmful levels. However, pregnancy-related hormonal changes can make your skin more sensitive, and prolonged exposure to bleach may cause irritation. Additionally, due to these hormonal shifts, your hair may react differently to bleach than it normally would.
What if I work as a cosmetologist while pregnant?
For those working as cosmetologists, the primary risk during pregnancy is the amount of exposure to hair treatment chemicals, which is influenced by the number of hours spent working and the environment in which you work. To minimize exposure, it’s essential to maintain proper working conditions, such as wearing protective gloves, avoiding eating or drinking in the work area, and ensuring that the space is well-ventilated. Taking these precautions can help limit your exposure to chemicals commonly found in hair treatments.
