Every week it’s the same story—washing your hair once, twice, maybe even three times, hoping they’ll look fresh and light. But instead, they turn dull, heavy, or greasy too quickly. What if, all along, you haven’t been using the secret ingredient for truly clean hair?

A natural trick is making a comeback: vinegar. Surprised? Not really. Experts have been talking about it for years. According to them, it’s a highly effective routine—but only if done right.

The benefits of washing hair with vinegar

Why you shouldn’t drink orange juice for breakfast despite what everyone thinks

Summer is just around the corner, bringing a craving for light, fresh hair that shines in the sun. Yet, between sweat, sand, and chlorine, your hair often ends up dull, flat, or greasy by the next day.

So how do you wash your hair without damaging it? A time-tested method is back in the spotlight, calling for vinegar—you probably already have a bottle sitting right in your kitchen.

This isn’t just some influencer’s hack. Dr. Carolina González Falcón, a dermatologist and pharmaceutical expert, has been recommending this to her patients for years. And she’s far from alone.

The MAN Medical Institute claims vinegar can “improve hair quality and shine, eliminate impurities from the roots, and deeply cleanse the scalp.” But there’s a catch: you must use it carefully.

Before you rush to grab that vinegar bottle, here’s a crucial tip: washing your hair with vinegar does not mean pouring it on like salad dressing.

“Vinegar has a high acidity and can damage the scalp if used improperly,” explains Dr. González Falcón. “Besides its strong smell, it shouldn’t be applied undiluted or left on the hair for too long.”

The secret? Dilution. Create a 50/50 mix of water and vinegar. Then, gently massage this mixture into your scalp. This motion not only cleanses but stimulates microcirculation at the roots, helping your scalp feel fresh and balanced.

After massaging, rinse thoroughly. Then, continue with your usual hair care routine—shampoo, conditioner, or hair masks—but opt for gentle, non-stripping products to protect your hair.

Not all vinegars are created equal when it comes to hair care. Experts usually recommend two safe options: apple cider vinegar for its sebum-balancing and anti-dandruff effects, and white vinegar, which is more purifying but demands extra caution.

Both work by closing the hair cuticle, reducing frizz, and boosting shine—a true miracle if used wisely.

The MAN Medical Institute advises using vinegar treatments just twice a week. It’s not a cure-all for serious scalp or hair issues like hair loss or severe dryness. In those cases, specialized care is essential.

Thinking back, I remember trying a vinegar rinse after a beach trip when my hair felt lifeless and oily from all the salt and sweat. I was skeptical at first, but within a couple of washes, my hair felt cleaner and lighter, with a noticeable shine that I hadn’t seen in weeks. The trick? Dilution and not overdoing it.
