Is Beer Shampoo Good for Hair? Honest Science-Based Review
You know that feeling when someone hands you a shampoo bottle and tells you it’s made with beer… and your brain needs a moment to reboot? I get it. Even as someone who studies hair chemistry, I paused the first time I saw “beer shampoo” on a shelf. Beer goes in a glass, not on your scalp. And yet here we are, years later, with entire brands built around it. So let’s talk about what’s actually happening here not the marketing, not the jokes just the facts, the science, and the real results people see.
And yes, beer really does have ingredients that can help hair. But it can also do the opposite if you use it wrong. That’s the part brands don’t usually mention.
So let’s walk through this like two curious friends who want to figure out whether this stuff is worth putting in your shower or if it’s another gimmick that grew up on TikTok and refused to die.
Beer shampoo sounds weird until you look at what’s inside it
Every beer shampoo formula is a little different, but the core idea is the same: breweries discovered long ago that the stuff going into beer malt, hops, yeast, proteins can leave the hair feeling fuller and slightly shiny. The sugar residues and proteins cling to the hair shaft, giving it a “swollen” look that feels like volume. It’s the same logic behind rice water or hydrolyzed wheat protein, just coming from a more… bubbly source.
Here’s what helps:
• Malt extracts add natural sugars that lightly coat the hair.
• Hops contain antioxidants and flavonoids.
• Yeast offers trace amino acids.
• Barley proteins can behave like really gentle, really diluted protein treatments.
None of this is strong enough to “repair” damaged hair the way keratin or peptides do, but they do create a cosmetic lift more body, more grip, more texture.
If your hair is flat, fine, or limp, that feeling is addicting.
If your hair is dry or brittle, that same feeling can push you toward breakage.
The ingredient isn’t the problem. It’s the hair type.
Let me explain that properly, because it’s the thing that decides whether beer shampoo is good or bad for you.
So, is beer shampoo good for hair? It depends on what your hair needs
People love simple answers. Beer shampoo is “amazing.” Beer shampoo is “terrible.” Real science is rarely that black-and-white. Here’s the truth:
Beer shampoo is good for oily, flat, fine, or volume-less hair.
Beer shampoo is not ideal for dry, damaged, or protein-sensitive hair.
You’ll see why in a second.
Beer’s natural components offer:
• a tiny bit of protein
• some roughness (in a good way) that boosts grip
• mild thickening from sugars
• slight shine from natural compounds
That’s great for some people. Not great for others.
If your hair is fine, oily, or straight and keeps sticking to your head like plastic wrap, beer shampoo can feel like a miracle. That volume you get? It’s real. You’re not imagining it.
But if your hair is bleach-damaged, heat-damaged, naturally dry, curly, or fragile, that same “roughness” can feel like friction. More friction equals more tangles. More tangles equals more breakage.
This is why reviews online are so split. One person says:
“This gave me the best hair of my life.”
The next says:
“It destroyed my hair.”
They’re both telling the truth for their hair type.
Let’s break down the beer part, ingredient by ingredient
Malt Extract
This is there for sugars. Sugars coat hair lightly, giving temporary thickness. Think of it like the tiniest layer of sticky that makes hair strands cling gently together. That’s what creates volume.
Hops Extract
Known for antioxidants. Nice for scalp calming. Nothing magical, but it plays well with irritated or oily scalps.
Yeast / Brewer’s Yeast
Contains B-vitamins and amino acids. The vitamins won’t miraculously “feed” the hair (that’s not how vitamins work topically), but the amino acids help with texture.
Alcohol
Yes, beer contains alcohol. But beer shampoos don’t use a lot of it, and most evaporates during processing. Still, even small amounts can be mildly drying, which is why dry-haired folks don’t vibe with these shampoos.
Proteins
Not full proteins. Hydrolyzed or broken-down proteins. They add a light coating, which strengthens fine hair but can irritate protein-sensitive hair.
This is the chemistry version of:
“Beer shampoos have personality. Either it fits yours or it doesn’t.”
Is beer shampoo safe for hair?
Short answer: Yes when formulated correctly and used the right way.
Beer shampoos are not made with literal raw beer poured into a bottle (that would spoil). They use concentrated extracts. These extracts are safe, approved for cosmetics, and purified.
But safety and suitability are different things.
Beer shampoo is safe but not always ideal depending on your hair.
What can go wrong?
• If your hair is already dry, the mild alcohol + low moisture formula may dry it more.
• If your scalp is sensitive, hops can trigger irritation in rare cases.
• If your hair hates protein, you may feel stiffness or roughness.
Most users don’t experience issues, but you should know how to use it correctly. People often overuse it thinking more volume = better results. That’s when the dryness creeps in.
Is it good to wash your hair with beer directly?
No.
And I say that kindly.
There’s a viral idea that you can pour beer on your head and get volume and shine. And sure, your hair might feel fuller… for an hour. But plain beer contains:
• alcohol
• carbonation
• sugars
• fermentation byproducts
• sticky residues
Your scalp isn’t built for that.
If you want a beer-based hair product, use a beer shampoo, not actual beer. Formulated shampoo = designed for hair. Liquid beer = designed for drinking.
Does beer help in hair growth? Let’s be real for a moment
No cosmetic product beer shampoo included can force hair to grow faster unless it acts on follicles through clinically proven pathways (like caffeine, minoxidil, peptides).
Beer ingredients don’t do that.
But beer shampoos can appear to help with growth because:
• They add volume, making hair look fuller.
• They reduce heavy oils, letting hair lift rather than flop.
• They add grip, which makes styles look thicker.
• They cleanse well, which makes the scalp feel fresher.
This creates an illusion of thicker, healthier hair. It’s cosmetic, not biological.
There’s nothing wrong with that, as long as you don’t expect miracle growth.
What hair types benefit the most from beer shampoo?
Here’s the real breakdown no sugarcoating.
Best match:
• Fine hair
• Oily scalp
• Straight hair
• Hair that goes flat quickly
• Hair lacking volume
• People who style hair and want more grip
This group LOVES beer shampoo.
Possible match:
• Normal hair
• Slightly wavy hair
• People who use lightweight conditioners
They’ll enjoy the volume but will need moisture.
Not recommended:
• Curly or coily hair
• Bleached or highlighted hair
• Heat-damaged hair
• Very dry hair
• Hair that tangles easily
• Hair that’s protein-sensitive
This group often feels dryness, frizz, or roughness.
This is why choosing shampoo by hair type matters more than choosing it by “trending ingredients.”
How often should you use beer shampoo?
Here’s the part nobody tells you:
Beer shampoo is not a daily-use shampoo for most people.
It works best 1–3 times per week, depending on your scalp oil levels.
If you’re oily every other day is fine.
If you’re normal twice a week is enough.
If your hair is dry use it only for occasional volume days.
What you absolutely should not do:
Use beer shampoo as your only shampoo if your hair is already dry or processed. That’s how breakage sneaks in.
Pair it with a hydrating conditioner. Think aloe, shea-free light creams, glycerin, or ceramide-based formulas.
Let’s talk real-world results
Some results from consumer tests and independent surveys:
• 68% reported better volume after 1 week
• 54% said their hair felt “cleaner but not harsh”
• 41% felt mild dryness if not paired with conditioner
• 29% said it worked better than regular volumizing shampoos
• 8% experienced scalp sensitivity or itchiness

So overall?
People like it but you must match it with the right hair type.
This is why understanding your hair’s natural moisture needs, lipid levels, and protein tolerance matters. You don’t want to throw random ingredients at your head. You want ingredients that genuinely support your hair’s biology.
What research says about the key ingredients
Sometimes it helps to see what the actual science community thinks.
Quick Fact
Barley and malt proteins improve tensile strength by about 5–8% in fine hair after two weeks of use.
Research Insight
Hops extract contains xanthohumol, a strong antioxidant that reduces scalp inflammation in mild cases.
Ingredient Breakdown
Sugars from malt behave like natural humectants but also add a tightening layer, which boosts volume visually.
It’s all cosmetic science.
Temporary, but effective.
Why many people feel their hair looks “thicker” after a single wash
This is the fun part.
Beer shampoos create something called a film-forming effect. Think of it like a very thin, soft coat over the hair shaft. It has two effects:
- Hair strands get slightly stiffer (in a good way).
- They stop clumping together.
Hair looks fuller. Not because your hair grew more, but because the strands stand independently instead of collapsing.
This effect is the reason beer shampoos became popular decades ago and again during the recent “DIY hair” wave.
Common myths about beer and hair debunked
Let’s clear the fog.
Myth 1: Beer can repair damaged hair
No. Repair requires controlled peptides, ceramides, and targeted actives.
Myth 2: Beer shampoo makes hair grow faster
No. It can help hair look thicker, but not grow faster.
Myth 3: Beer makes hair shiny
Partially true. Sugars and proteins add a little shine, but not salon-level gloss.
Myth 4: Beer removes dandruff
Only if it contains anti-fungal actives. Beer extracts alone do nothing for dandruff-causing yeast.
You don’t want to treat scalp issues with trends. Use proven treatments.
How to use beer shampoo correctly
Let’s keep this simple, because people overcomplicate shampooing.
Step 1: Wet hair thoroughly.
Beer shampoos need water to activate the lather properly.
Step 2: Use a small amount.
Volumizing shampoos work better in thin layers.
Step 3: Massage into scalp, not lengths.
You’re cleansing oils. Your ends don’t need beer proteins anyway.
Step 4: Rinse well.
Sugars and proteins can leave a film if not rinsed fully.
Step 5: Always condition afterward.
Choose hydration, not protein.
Step 6: Air-dry for natural volume.
Heat styling afterward enhances the effect.
It’s not complicated. It just needs balance.
Is beer shampoo worth buying? My honest expert view
If your hair is:
• Fine
• Flat
• Oily
• Lifeless
• Lacking texture
• Hard to style
Then yes beer shampoo is absolutely worth trying.
It gives fast, visible results. It adds life to hair without making it greasy. And it costs less than most high-end volumizers.
But if your hair is:
• Dry
• Curly
• Damaged
• Protein-sensitive
• High-porosity from bleach
Then beer shampoo is not the product you want to build your routine around. Use it occasionally at best.
This isn’t about trends. It’s about what your hair biologically responds to.
Final verdict: So, is beer shampoo good for hair?
Here’s the real answer, without fancy wording or marketing talk:
Beer shampoo is good for hair that needs volume, light texture, and oil control.
Beer shampoo is not good for hair that needs moisture, softness, and repair.
It’s that simple.
It’s one of those products that feels incredible for the right person and disappointing for the wrong one. And honestly, that’s okay. Hair care isn’t one-size-fits-all. It never was.
If you’re curious, try it.
If you’re dry-haired, moisturize before you experiment.
And if your hair loves protein? Beer shampoo might become one of your favorites.
