Like BV, a yeast infection is frequently the result of vaginal pH being out of whack, says Dr Wendy Askew, a board-certified ob-gyn at the Institute for Women's Health in San Antonio. They can occur at random or following antibiotic use, sex, stress, or a change in diet (and women with diabetes have a higher risk). In addition to itchiness, you may also notice curdled, white, or thick discharge. The good news is that you can go ahead and use an OTC remedy, like Monistat, which should take care of the symptoms within a day or so. To avoid recurrent infections, Askew recommends taking a probiotic with a high bacteria count of acidophilus, like Flora-Q, which will help keep yeast in check.
This skin irritation is caused by allergies to certain products, says Brett Worly, assistant professor in the department of obstetrics and gynecology at the Ohio State University. You can get it from anything with perfumes or additives, including condoms and lubricants, and on top of itching, you may also notice redness, swelling, and skin thickening. It can also be the result of shaving, says Askew. If you know that you’re susceptible to vaginal irritation, use hypoallergenic hygiene products, like shampoo, fabric softeners, and laundry detergents, making sure to avoid chemicals, soaps, and irritating lubricants, says Worly. Even toilet paper with scents or colors can be troublemakers. Plus, you should definitely avoid shaving if you're sensitive—and never, ever douche. The vagina is self-cleaning, so you don't need to put anything on or in it, says Streicher.
Eczema or Psoriasis
Genetic skin disorders like these two can cause redness and itching in the genital region, along with a patchy or rash-like appearance. If you’re diagnosed with either, a mild steroid like hydrocortisone and taking oatmeal baths can help alleviate the discomfort, says Askew. If you don’t feel relief within a week, ask your doctor about other treatment options.
Sexually Transmitted Diseases (STDs)
We shouldn’t have to tell you this again, but unprotected sex can lead to an STD (which is why you always, always need to use protection). And a bunch of them can make your lady parts itch, including chlamydia, herpes, trichomoniasis, and gonorrhea. Crabs, or pubic lice, can also appear in women with hair down there. With any of these, the itching (or tingling sensation) can progress to pain and burning, says Askew. If you experience itching along with any other common STD symptoms like burning while you pee, foul-smelling discharge, sores on your genitals, and pain during sex, you should book it to your gyno to get tested ASAP. If you do test positive for an STD, your doctor will give you either injectable or oral antibiotics, or an antiviral medication in the case of herpes, says Askew.
This serious condition and cause of vulvar itching appears as white spots on the skin, says Streicher. While it can come out of nowhere, some medical professionals think hormones or an overactive immune system may have something to do with it. Lichen sclerosus needs to be diagnosed by a gynecologist and treated with prescription medication.

Anytime your hormones levels change or fluctuate (like during your period, pregnancy, menopause, or while you're taking birth control), you may experience vaginal itching. Dryness is another indicator that hormones could be to to blame for your pain. When it comes to your period, the products you use during that time of the month (like pads and panty liners) often contain fragrances or colors that can add to the discomfort. If this happens to you often, consider trying a menstrual cup or organic cotton products, which may be less irritating. However, it may be difficult to pinpoint if your birth control prescription is what's causing you to itch down there (sometimes the only way to know if this is the culprit is to stop or start hormonal contraception, says Worly). With any of these hormonal changes, your doctor might prescribe a hormonal cream to apply topically and you can also ask about switching pills if the itch continues to be a persistent problem.
