What is apple cider vinegar?

Apple cider vinegar is made by fermenting apple juice and contains acetic acid, which makes it acidic. Being natural or used in cooking does not automatically make it gentle on hair or scalp. A formulated hair rinse and kitchen vinegar are different products.

Which benefits are supported?

Rinses are often discussed for shine and a cleaner feel, but research on hair and scalp use is limited. A change in how hair feels does not demonstrate increased growth, a normalised scalp or dandruff treatment. We do not recommend apple cider vinegar as a treatment for hair loss or skin disease.

Dilution and recipes

Never use undiluted apple cider vinegar on hair or skin. Acetic acid can irritate and, in severe cases, cause burns. No homemade recipe has been shown suitable for everyone: strength, amount and skin condition matter. For a cosmetic product containing vinegar, follow that product's instructions. Do not add extra vinegar or essential oils.

How to approach a hair rinse

Prefer a product intended for hair with clear directions. Test on a small area first; this does not guarantee that irritation will not occur. Avoid contact with eyes and broken or irritated skin. Do not use a rinse as a leave-in or overnight treatment unless a formulated product is expressly intended for that use. Rinse as directed and stop immediately if stinging, redness or discomfort develops.

How often, and before or after conditioner?

There is no well-established standard frequency for homemade vinegar rinses. More and stronger is not better. Follow the product's instructions on when and how often to use it rather than a recipe from social media. Use conditioner according to its own directions; vinegar does not replace its detangling and softening functions. Take extra care with coloured, bleached or fragile hair.

What about dandruff and scalp detox?

Product buildup, oil and dandruff are different problems. Detox does not describe a demonstrated removal of toxins from the scalp. A pharmacist can advise on suitable dandruff shampoo. With eczema, psoriasis, sores or persistent itching, avoid vinegar experiments and seek professional advice. Seek medical advice for severe irritation, swelling or persistent symptoms.

A simpler routine for buildup

Start with shampoo suited to your scalp and hair, thorough rinsing and an appropriate amount of conditioner on the lengths. For persistent deposits, a cleansing shampoo used as directed may be more relevant than further homemade mixtures. The shampoo below is an option for regular cleansing, not a medical treatment or a proven way to remove toxins.

Questions about apple cider vinegar for hair

Can apple cider vinegar make hair grow faster?

There is insufficient clinical evidence to recommend apple cider vinegar as a hair-growth treatment. Extra shine or less product buildup is not the same as increased growth.

Do I need raw, unfiltered vinegar with the mother?

Sediment or the mother has not been shown to make a hair rinse better. Do not choose a product on that assumption, and never apply undiluted vinegar to the scalp.
