How Can Apple Cider Vinegar Help With Hair Loss?

Shedding 50 to 150 hair strands a day is normal (3). Hair loss can happen due to a variety of reasons. Factors like stress, illness, and nutritional deficiencies can affect hair growth (4).

Following are the various ways apple cider vinegar may help treat hair loss:

  • Balances Hair pH

The pH of hair is 4 to 5, making it slightly acidic. Maintaining the natural pH of hair is crucial to protect it from external damage, and to keep it healthy, smooth, and shiny. However, most shampoos on the market have an alkaline pH. This could alter the natural hair pH and lead to cuticle damage and harm the hair fibers (5).

Apple cider vinegar contains acetic acid and has a low pH (is acidic) (6). Theoretically, using it may restore the natural hair pH. However, more studies are warranted in this regard.

  • May Remove Scalp Build-Up

Using different hair products, sweat accumulation, and oil secretion can cause scalp build-up and eventually lead to irritation.

A diluted apple cider vinegar solution may help remove scalp build-up. However, more research is required in this regard.

  • May Boost Hair Follicle Growth

Poor blood circulation to the hair follicles could inhibit hair growth (7). Some believe that apple cider vinegar may improve blood circulation. The antibacterial properties of apple cider vinegar may help cleanse the scalp and the hair follicles. This may promote hair growth.

  • May Boost Hair Shine

Apple cider vinegar may help smoothen the hair cuticle (the outermost protective layer of the hair). The acetic acid in ACV reduces frizz and restores hair pH, which could have been altered by alkaline shampoos. Its amino acids and fatty acids may boost hair shine (8).

  • May Help Treat Dandruff

Apple cider vinegar has anti-fungal properties (9). It may help in dandruff treatment. Some believe its high acidity could make it difficult for the fungus to thrive. However, more research is required in this aspect.

  • May Fight Free Radicals And Premature Aging

If your doctor recommends, go for an apple cider vinegar supplement. But ensure you stick to the dosage. Excess intake of ACV for a prolonged period can cause hypokalemiai  XA condition where the potassium levels in the blood are too low, resulting in weak muscles, twitches, cramps, etc. or aggravate osteoporosisi  XA medical condition that causes brittle and fragile bones due to decreased bone mineral density and bone mass. (12).

One way of making the best out of ACV is knowing the right type you need to purchase. With a variety of options on the market, this could be a challenge. The next section will help you understand how to pick the best apple cider vinegar.

How To Choose The Best Apple Cider Vinegar

Here are the factors to be considered before you purchase apple cider vinegar.

  1. Filtered/Unfiltered: This does not matter if you are using ACV for a rinse alone. But if you are consuming it, unfiltered ACV is better as it will contain more nutrients.
  2. The “Mother”: The ‘mother’ is obtained from the fermentation process. It comes with brown cobweb bits floating at the bottom. It may look like it has gone bad, but actually is beneficial.
  3. Unpasteurized: You may purchase ACV that has not gone through any heating process. Unpasteurized ACV retains most of its good bacteria.
  4. Organic: Organic apple cider vinegar is ideal. One can also look for ’raw’ apple cider vinegar that has no artificial flavors or chemicals.

Choosing the right kind of apple cider vinegar may not necessarily mean it is safe for all. ACV could cause side effects in some. It also may show adverse effects if not used in the right way.

Risks Of Using Apple Cider Vinegar

  • Undiluted ACV: Apple cider vinegar has a low pH and is highly acidic. Using it undiluted may cause scalp issues. Some research shows that apple cider vinegar could cause chemical burns on the skin (13). An ACV rinse must always be used diluted.
  • Excess Use Of ACV: Using a highly acidic solution too often may cause more harm. Use the ACV rinse only twice a week.
  • Allergies: Some anecdotal evidence suggests that ACV could cause skin allergies. However, relevant research is lacking. You may do a patch test before using ACV on your skin/hair. If you observe a reaction, stop use and consult a dermatologist.

Using a minimal amount of ACV and diluting it with water is always safe. You may gradually increase the amount of vinegar as the weeks pass.

The anti-fungal, anti-viral, and antibacterial properties of apple cider vinegar make it an excellent solution to fight against hair care issues. You may also use apple cider vinegar for hair loss issues. It helps boost scalp health by removing build-up, improving blood circulation, smoothening the hair cuticle, and treating dandruff. You can use ACV as an external rinse or a supplement in your hair care routine. However, since ACV is highly acidic, dilute it before using it. Consult your doctor to learn more about the dosage and ways to use it.
