During pregnancy your hair may feel fuller, but you might not be growing more hair (the strands are not any thicker). You might just be losing them more slowly than you usually do. All woman experience varying degrees of hair changes during pregnancy.
Here’s what happens: typically, 85 to 95 percent of the hair on your head is growing. The other 5 to 15 percent is in a resting phase. After the resting period, this hair naturally falls out (quite common when you are brushing or shampooing your hair) and is substituted by new growth. Generally, woman sheds about 100 hairs a day.
During pregnancy, higher levels of estrogen extends the growth phase, resulting in less shedding of hair and thicker locks. In some cases, women also notice that their hair becomes shinier during pregnancy or that it changes in texture (for example – curly hair might become straighter).
Your hair may not look as good postpartum. After giving birth, the growth/rest cycle goes back to its previous arrangement, so you may notice more hair falling out.
Having said all this, not all pregnant women notice dramatic changes in their hair before and after giving birth, though. These changes tend to happen more in women with longer hair.
Is it common to have more facial or body hair?
Unfortunately, facial and body hair may also grow faster during pregnancy, perhaps because of an increase in hormones called androgens. These cause the hair changes during pregnancy.
To get rid of these unwanted sudden growth of hair, you can safely tweeze, wax, or shave. Avoid chemicals such as bleaches, which could be absorbed into the bloodstream through the skin pores.
Permanent hair-removal techniques, like laser and electrolysis, are supposed to be safe. However, the hormones that cause chloasma or the mask of pregnancy can also cause further darkening of the skin after these cosmetic procedures. Moreover, while they are considered safe – laser and electrolysis can be painful. Pregnancy on its own has plenty of discomfort, why would you want to add some more.
Mostly, this unwanted hair goes away in three to six months after you deliver your baby.
