Vaginal Hygiene: What Helps, and What to Stop Doing

The vagina cleans itself. Most hygiene products work against it, not with it.

Spend five minutes in any pharmacy and you will find an entire aisle dedicated to "feminine hygiene" - wipes, washes, sprays, deodorants, and douches. Almost none of these products are necessary. Several are actively harmful. Understanding what the vagina actually needs (and does not need) to stay healthy is far simpler than the marketing suggests.
The vagina is not a passive cavity - it is a dynamic ecosystem. A healthy vaginal environment is dominated by Lactobacillus bacteria, which produce lactic acid and hydrogen peroxide to maintain a pH between 3.8 and 4.5. This acidity is the primary defence against pathogens. The entire system is self-regulating: the vagina produces fluid that carries away dead cells, excess bacteria, and other material. This is normal discharge, and it is part of the cleaning process, not a sign that something needs to be washed away.
Disrupting this ecosystem is easy. The lactobacilli that maintain vaginal pH are sensitive to changes in their environment. Introducing alkaline products, chemicals, or even excessive water into the vaginal canal shifts the pH upward, reducing the protective bacterial population and creating conditions where harmful bacteria or fungi can establish themselves.
Douching is the clearest example of a hygiene practice that causes the very problems it claims to prevent. Pushing water or any other liquid into the vaginal canal displaces the existing bacterial community and temporarily neutralises the acidic pH. Regular douching has been consistently linked to higher rates of bacterial vaginosis (BV), a condition characterised by an overgrowth of anaerobic bacteria that produces the unpleasant odour douching is often used to address. In other words: douching creates the odour problem it is marketed as solving.
Scented soaps, "feminine washes," and intimate wipes have a similar problem. Most soaps are alkaline - their pH typically sits between 9 and 11. Washing with them around and inside the vulva raises local pH and can irritate the sensitive mucosal tissue. Fragrances in particular are a common cause of contact dermatitis and vulvar irritation. Many gynaecologists recommend nothing more than warm water on the external vulva for routine cleaning.
Scented panty liners and pads used every day (rather than during menstruation) trap moisture, raise local temperature, and create an environment that encourages yeast overgrowth. The same applies to tight synthetic underwear worn for extended periods.
For the vast majority of people, the following is sufficient: wash the external vulva - the outer and inner labia, the clitoral hood, the perineum - with warm water. If you prefer to use soap, choose an unscented, mild, pH-balanced product and use it only on the external skin, not inside the vaginal opening. Rinse thoroughly. Pat dry rather than rubbing.
Underwear choice matters more than most people realise. Cotton is breathable and absorbs moisture rather than trapping it against the skin. Synthetic fabrics like nylon and polyester hold heat and moisture, creating conditions that favour yeast and bacterial growth. Sleeping without underwear occasionally allows ventilation that daytime clothing does not permit.
After using the toilet, wiping front to back keeps intestinal bacteria away from the vaginal and urethral openings. This single habit significantly reduces the risk of urinary tract infections and is one of the few hygiene recommendations with clear evidence behind it.
Menstrual products should be changed regularly - tampons every four to eight hours, menstrual cups cleaned as directed by the manufacturer. Leaving products in place for longer than recommended creates a warm, moist environment that increases infection risk.
Pubic hair has no hygiene requirement for removal. This is not a matter of preference being wrong in either direction - it is a matter of what the biology actually shows. Pubic hair acts as a physical barrier, reducing skin-to-skin friction during sexual activity and keeping external pathogens at a distance from the vaginal opening.
Shaving, in contrast, creates small micro-abrasions that compromise the skin barrier. Research by DeMaria and colleagues in 2014 found that pubic hair removal was associated with higher rates of contact injuries and skin infections, with shaving carrying more risk than waxing or trimming. The same study noted that complete removal was becoming more common despite the absence of any hygiene benefit - a pattern driven by aesthetic preference and cultural norms rather than medical recommendation.
If you choose to remove pubic hair, using a clean, sharp razor with shaving gel, shaving in the direction of hair growth, and keeping the area moisturised afterward reduces (but does not eliminate) the risk of ingrown hairs and folliculitis.
Normal vaginal discharge varies throughout the menstrual cycle. Around ovulation it is typically clear, stretchy, and more abundant - sometimes described as similar to raw egg white. At other points in the cycle it may be thicker and white or slightly yellowish. A mild, slightly tangy odour is within the normal range and reflects the acidic pH of a healthy vaginal environment. Discharge that stains underwear a yellowish colour after drying is also normal oxidation, not a sign of infection.
Changes that warrant a visit to a doctor include: a sudden shift to a grey or green colour; a strong fishy odour, particularly after sex (a characteristic sign of BV); a thick, white, cottage-cheese-like texture accompanied by itching (consistent with a yeast infection); unusual amounts of discharge combined with pelvic pain or burning during urination; or any bleeding outside of an expected menstrual period.
Bacterial vaginosis and yeast infections are different conditions that require different treatments. BV is treated with antibiotics; yeast infections are treated with antifungal medication. Using an antifungal for BV will not work, and vice versa. If you are unsure which you have, a clinical diagnosis - which involves a simple swab test - is more reliable than self-diagnosing from symptoms alone.
