Beer and Benefits for Hair Growth

BY Rebi September 1, 2025

When you think of hair growth solutions, beer probably isn’t the first thing that comes to mind. But the beer and benefits for hair growth story is more than just a quirky folk remedy. Beer contains a cocktail of nutrients — proteins, B-vitamins, minerals, and even silicon — that may help strengthen, condition, and add volume to your hair. While scientific backing is limited, many use beer as a topical treatment (rinse or mask) to improve shine and scalp health.

What’s in Beer That Might Help Hair

Here are the key components found in beer that are often credited with supporting hair:

  1. Proteins from Malt and Hops
    • Beer is brewed from malted grains, which contain proteins. These proteins may help coat and strengthen hair strands.
    • Although there’s no rigorous proof that topical beer delivers these proteins into the hair shaft, anecdotal users report smoother, more resilient hair.
  2. B-Vitamins
    • Beer contains several B-vitamins, including B2 (riboflavin), B3 (niacin), B6, B12, and folate, which are often linked with hair health.
    • These vitamins help in energy metabolism and may indirectly support the maintenance of hair follicles.
  3. Minerals & Trace Elements
    • Silicon: Beer is a reasonably good dietary source of biologically available silicon, which may contribute to stronger connective tissues, including hair.
    • Iron, magnesium, potassium, and selenium are also present in beer ‒ all of which are helpful (in small amounts) for overall hair and scalp health.
  4. Yeast & Antioxidants
    • The brewer’s yeast used in fermentation contains nutritional compounds that are sometimes credited with promoting a healthy scalp.
    • Hops, another ingredient in beer, deliver flavonoids and antioxidants, which may reduce oxidative stress on the scalp.
  5. Sugars and pH
    • Natural sugars in beer (maltose and sucrose) can help smooth the hair cuticle, improving shine.
    • Beer’s slightly acidic pH might help close the hair cuticle, making hair appear smoother and less frizzy.

Potential Hair Benefits of Beer

Based on its nutrient profile and traditional use, these are some of the benefits people and beauty experts associate with using beer for hair:

  • Strengthens Hair: Thanks to protein from malt and hops, beer may help reinforce hair strands and reduce breakage.
  • Adds Volume: The combination of proteins and sugars can make hair look fuller by coating each strand and giving it body.
  • Improves Shine: Beer’s components can impart a healthy luster to dull hair.
  • Scalp Conditioning: Some suggest beer can help cleanse the scalp, reduce dandruff, and create a healthier scalp environment due to its yeast and mild astringent effect.
  • Natural Conditioner Alternative: When used as a rinse, beer may soften and smooth hair, acting somewhat like a lightweight, natural conditioner.

How to Use Beer on Your Hair Safely

If you want to try beer for hair growth, here are methods people commonly use — and tips to do it safely:

  1. Flat Beer Rinse
    • Let a beer sit (uncovered) until it becomes flat.
    • Shampoo your hair normally, skip or reduce conditioner.
    • Pour the flat beer over damp hair and massage gently into the scalp.
    • Leave it on for about 10–15 minutes, then rinse thoroughly with cool water.
    • Use 1–2 times a month. Experts caution that frequent usage can be drying due to the alcohol content.
  2. Beer Hair Mask
    • Mix ½ to 1 cup of flat beer with other nourishing ingredients such as:
      • Egg yolk for protein
      • Coconut or avocado oil for moisture
      • Honey for shine and hydration
    • Apply the mixture to scalp and hair, cover with a cap, and leave it on for 20–30 minutes (or up to an hour for a deeper mask).
    • Rinse thoroughly, then wash and condition as usual.
  3. Use Non-Alcoholic Beer Option
    • For people concerned about alcohol drying out their scalp, non-alcoholic beer offers similar nutritional benefits (especially from hops) without the alcohol.
    • Pour it as a rinse or use it in masks similarly.

Important Precautions & Considerations

  • Limited Scientific Evidence: While beer contains many beneficial nutrients, there is no robust clinical research proving that topical beer significantly enhances hair growth.
  • Patch Test: Alcohol in beer can irritate some scalps — always do a patch test before widespread use.
  • Overuse Risk: Frequent application can dry out hair due to the alcohol content and disrupt normal scalp health.
  • Hair Lightening: Beer may slightly lighten hair color (especially lighter hair tones) with repeated use.
  • Diet Is More Important: Relying on beer alone for nutrients is not ideal — a balanced diet with rich sources of B-vitamins, protein, and minerals should remain your primary strategy.

Final Thoughts

The idea of beer and benefits for hair growth is intriguing — beer does contain a mix of proteins, B-vitamins, silica, and antioxidants that may support hair strength, shine, and scalp health. While the scientific proof isn’t strong, many people enjoy beer-based rinses or masks as a natural, low-cost hair-care ritual. If you decide to try it, use flat beer or non-alcoholic beer, limit the frequency, and temper your expectations — it’s a supplementary care trick, not a cure-all.
