Yeast Hair Loss
Beer yeast is the ingredient Korean shampoo brands reach for when a bottle is aimed at thinning hair, and this collection holds 101 in-stock products built around it. MEDISURE, JSOOP, CHAKAN, BIER LAB and KUNDAL all sell a version, mostly as a 490ml to 1000ml scalp shampoo, with matching treatments in smaller 200ml tubs. A few things shape how the grid reads. KUNDAL splits its Beer Yeast line by scent, so Herb Mint, Citrus Pomelo and Pigmint Tea are the same idea in three fragrances. Several bottles are sold as four-packs, and BIER LAB keeps an older 490ml packaging record alongside its current one. Decide on format first, shampoo or treatment, then on scent.

Beer yeast shampoo for thinning hair
Beer yeast, usually printed as beer yeast or brewer's yeast on Korean labels, is one of the most common anti-hair-loss claims in the category. It brings B vitamins, amino acids and biotin into a scalp product, and Korean brands build whole lines around it. This guide covers what the grid actually contains, how the brands here differ, and how to use a bottle so you can judge whether it did anything.
What beer yeast is doing in a shampoo
Brewer's yeast is a protein-rich fermentation by-product, and the extracts used in these shampoos carry B-group vitamins and amino acids. In a rinse-off product the realistic goal is scalp condition: less flaking, less irritation, a cleaner follicle opening. That is worth having, because an inflamed or heavily oiled scalp makes shedding worse. Treat it as support for the scalp environment rather than a growth drug, and give any bottle a full three months before deciding.
Shampoo, treatment, or both
The shampoos on this page run 490ml to 1000ml and do the cleansing work, so they are where the scalp contact happens. The treatments are smaller, typically 200ml, and go on the lengths after rinsing to handle the dryness that a clarifying scalp shampoo can leave behind. KUNDAL sells them as matched pairs, a 500ml Beer Yeast shampoo with a 200ml treatment in the same scent. If your ends are already fine, the shampoo alone is enough.
The KUNDAL scent split
KUNDAL fans its Beer Yeast Hair Loss line across fragrances rather than formulas: Herb Mint, Citrus Pomelo and Pigmint Tea appear as 500ml shampoos, and Herb Mint and Citrus Pomelo also as 200ml treatments. Herb Mint is the cooling one and the usual pick for oily scalps in summer. Citrus Pomelo is the lighter, sweeter option. Pigmint Tea sits between them. Choose on scent, since you will be smelling it every day, and expect the actives to be shared.
Who makes what here
MEDISURE runs a 1000ml Beer Yeast Hair Loss Shampoo, the largest single bottle in the grid and the cheapest per millilitre. JSOOP's Deep Green J version comes as 500ml bottles sold four at a time. CHAKAN's Beer Yeast Bomb is a 500ml with a stronger cleansing pitch. BIER LAB builds its whole identity on beer yeast and sells a 490ml Relief Shampoo, also in four-packs, next to an older 490ml packaging record. KUNDAL is the scent-led range described above.
Why so many four-packs
Scalp shampoo is a long commitment, and Korean brands price around that: JSOOP and BIER LAB both list their 500ml and 490ml bottles as sets of four. That is roughly six months of daily washing for one person. Buy a single bottle first to check the scent and how your scalp reacts, then move to a four-pack for the stretch where you are actually judging results.
Getting the shampoo to work on the scalp
Most people wash their hair and barely touch their scalp. Wet thoroughly, work the lather onto the skin with fingertips rather than nails, and leave it there for two or three minutes before rinsing. A second short wash on very oily days is fine with these formulas. Rinse until the water runs clear, since residue is itself a source of itching, and dry the scalp rather than leaving it damp under a towel for an hour.
What to expect and when
Hair grows in cycles measured in months, so nothing visible happens in two weeks. What tends to change first is comfort: less itch, less oil by the evening, fewer flakes. Reduced shedding in the shower drain is the next signal, usually somewhere between six and twelve weeks. If shedding is sudden, patchy, or comes with a sore scalp, that is a dermatologist's question and no shampoo is the answer.
Pairing with the rest of a scalp routine
A beer yeast shampoo sits well under a leave-on scalp tonic, which stays on the skin all day and does not get rinsed away. Keep silicone-heavy conditioners off the roots and use them from the mid-lengths down. If you also use a scalp scrub, once a week is plenty alongside daily washing with these formulas, which already lean towards deep cleansing.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
Does beer yeast shampoo really help with thinning hair?
The honest answer is that it works on the scalp rather than on the follicle. Brewer's yeast extract brings B vitamins and amino acids to a rinse-off product, which helps with oil, flaking and irritation, and a calmer scalp sheds less. Products like the MEDISURE 1000ml or BIER LAB 490ml Relief Shampoo are worth three months of consistent use before you judge them. They are not a substitute for medical treatment of pattern hair loss.
Which KUNDAL Beer Yeast scent should I pick, Herb Mint, Citrus Pomelo or Pigmint Tea?
All three 500ml shampoos share the beer yeast base, so this is a fragrance decision. Herb Mint is the cooling one and suits oily scalps and hot weather. Citrus Pomelo is lighter and sweeter. Pigmint Tea sits in between. Herb Mint and Citrus Pomelo also have matching 200ml Beer Yeast Hair Loss Treatments if you want the pair in one scent.
Do I need the 200ml treatment as well as the shampoo?
Only if your lengths feel dry. The shampoos here are the part that touches the scalp and do the actual work. The treatments are conditioners for the mid-lengths and ends, useful because a clarifying scalp shampoo can leave longer hair rough. Short hair or an oily scalp usually does fine on the shampoo alone.
Why are the JSOOP and BIER LAB bottles sold four at a time?
Because judging a scalp shampoo takes months, and the brands price for that. JSOOP's Deep Green J 500ml and BIER LAB's 490ml Relief Shampoo both appear as four-packs, which is roughly half a year of daily washing for one person. Try a single bottle for the scent and the feel first, then buy the set for the period you are actually measuring.
How often should I wash with a beer yeast hair loss shampoo?
Daily is fine and usually better than every other day, because the point is keeping the scalp clean. Massage the lather into the skin with fingertips and leave it for two or three minutes before rinsing, which most people skip. On very oily days a second short wash does no harm with these formulas.
What is the difference between the two BIER LAB 490ml bottles?
One record is marked (Old) and carries the earlier packaging for the same Beer Yeast Hair Loss Shampoo; the current listing is the Relief Shampoo at the same 490ml fill. If both are in stock, treat them as the same product in different bottles and buy on price and pack size rather than hunting for a formula difference.
