Brittle hair? You can count on Kérastase Densifique to take your locks back from the brink. Thanks to a blend of wheat protein,ceramides,and gluco-peptides, this strengthening shampoo fortifies, plumps, and protects fragile hair.

2.BEST BUDGET:SIMFORT Carbonic Acid Shampoo

View on Amazon


  • It helps with flaky scalp
  • Improves scalp health by increasing blood flow and reviving dead follicles
  • Unclogs scalp pores
  • It helps with excess sebum production


  • Not a big bottle

Simfort uses Carbonc acid to help remove extra buildup in the pores on your scalp. On top of it being a DHT blocker, it does an excellent job of unclogging pores, which can make it difficult for hair follicles to produce hair effectively. Once the pores are free from sebum and build-up, oxygen enters the follicle, and blood flow increases. These two things are key when it comes to hair growth.

It comes out in a thick foam that is easy to spread throughout the hair. Although the packaging is quite small compared to usual shampoo bottles, a little bit goes a long way with this consistency.

3.BEST EXFOLIATING:Marc Anthony Grow Long Biotin Shampoo

What We Like

  • Budget-friendly
  • Stimulates scalp
  • Helps prevent breakage

What We Don’t Like

View on Amazon


  • Comes in a large 16 oz. bottle
  • It also has biotin, collagen, and tea tree oil
  • Stimulates blood flow to the follicle
  • It helps make the hair stronger
  • Cruelty-Free


  • It does have some light sulfates

This shampoo has a plethora of scalp and hair-enhancing ingredients on top of carbonic acid, such as tea tree, collagen, and biotin. Tea tree revitalizes the scalps and sort of gives it a wake-up call to kick those follicles into action, as well as help with common skin problems, like dandruff and psoriasis. Collagen and biotin are both ingredients that help with aging hair and skin.

While this shampoo does address a few other concerns with the extra ingredients, like damaged hair and dry scalp, there is sulfate in it as well. This isn’t always a bad thing, especially if you suffer from extra build up on the scalp. Just make sure you are use a really good conditioner with it.

This shampoo has many ingredients with DHT blocking abilities, such as rosemary, pumpkin seed, and nettle leaf extract. If your hair is starting to thin due to DHT, this is definitely the product for you. However, if you are already noticing balding, this shampoo will not help you. It simply helps keep more hair from falling out.

This shampoo is also free from all the bad stuff that dries out your skin and hair, like sulfates and harsh preservatives. It is also gluten-free and vegan, so it is great for those with allergies.

  • Trichologist-recommended
  • Contains salicylic acid and keratin
  • Helps prevent shedding

What We Don’t Like

  • Expensive

“Nanogen 7-in-1 Shampoo contains salicylic acid, glycerin, and hydrolyzed keratin,” says Holden. In other words, it checks all the boxes for boosting hair growth, exfoliating the scalp while strengthening the hair shaft.

In addition to cleansing and clearing away dead skin cells, this in-shower treatment works to moisturize, condition, and thicken your hair. What’s more, Nanogen calls on beta-glucan and plant-based antioxidants to fortify each strand and prevent shedding.

8.BEST FOR NATURAL HAIR:Fortero Carbonic Acid Shampoo

View on Amazon

  • Free of sulfates, parabens, and harsh chemicals
  • It gives your scalp a super fresh, clean feeling

Fortero is very similar to Simfort in that its focus is to clean out blocked hair follicles so that blood flow can contain and oxygen may enter.

The foamy shampoo spreads well and removes any build-up from excess sebum production and flaky scalps.

This product seems to work best when used with the whole set, including the shampoo, moisturizing conditioner, and minoxidil serum. Minoxidil is a medication that helps with hereditary baldness. Between the carbonic acid shampoo and serum, one of these ingredients is sure to help with your hair loss.

9.BEST FOR THINNING HAIR:Oribe Serene Scalp Anti

What We Like

  • Contains salicylic acid and keratin
  • Soothes irritation

What We Don’t Like

What to Look For in a Hair Growth Shampoo

Scalp Support

When it comes to growth-boosting shampoos, board-certified dermatologist Dr. Dendy Engelman recommends looking for a product that supports overall health of your scalp in addition to your hair cuticle and hair follicle. “The scalp plays an important role in growing and maintaining strong, healthy hair,” she says. Therefore, you want to make sure it’s being properly nourished and treated for optimal hair health and growth.

Stimulating Ingredients

Dr. Engelman also stresses the importance of using a formula that contains stimulating ingredients, such as biotin, zinc, niacin, peppermint, and caffeine. “These stimulate blood flow to the scalp and nutrient delivery to the hair follicle, promoting hair growth,” she says. That said, the more of these ingredients a product contains, the better.

Conditioning and Moisturizing Ingredients

Hair that’s dry and stripped of its natural oils won’t lead to healthy growth, so Dr. Engelman recommends looking for products that also contain conditioning and moisturizing ingredients. “These are key because they keep the strands healthy and strong.”

What Is carbonic acid shampoo?

Multi-functional carbonic acid shampoo stimulates hair development by stimulating hair follicles. The enhanced oxygen supply, in particular, aids in activating hair cells, adding moisture, and the general activation of the hair structure.

Regular shampoo generates a little foam, while carbonic acid shampoo generates a thick foam that leaves you feeling refreshed thanks to the numerous bubbles created by the acid.

Carbonic acid is produced primarily via the reaction of CA with SB. Carbonic acid shampoo does not enable germs to live because CA is naturally acidic, and SB is alkaline. The pH balance of carbonic acid shampoo is 5.5, which is the most suited acidic form for the scalp and is also the safest.

Ingredients In Carbonic Acid Shampoo

You may ask yourself, “why would I buy a shampoo with acid in it?” Good question, but there’s no need to panic. The carbonic acid shampoo is made from only natural plant extracts.

It is free of any potentially dangerous chemical compounds. It’s a perfectly safe product that has passed several countries’ hygiene standards. It is undergoing extensive study and will eventually provide scalp-treating items to address hair loss. This shampoo’s plant components can help keep the scalp clean and healthy and give your hair a nice shine.

The other main component of carbonic acid shampoo is DHT blockers. Dihydrotestosterone (DHT) is a hormone that causes various hair loss. DHT is produced by a bodily enzyme that converts testosterone into a byproduct.

Hair loss can result when DHT receptors interact with the estrogen receptors in the follicle. Miniaturization occurs when the follicles shrink to the point that they no longer produce hair. People genetically predisposed to DHT shrinkage may have female and male pattern baldness as a result.

What Can DHT Do For Hair Loss?

The answer varies, as it does with many hair growth and hair loss products. Some things work for some people while others do not. DHT blocker ingredient shampoos, such as carbonic acid shampoos, may benefit you. Many people believe that DHT is the source of hereditary hair loss. Thus, limiting it may result in less hair loss and a better chance of future growth.

DHT must cause hair loss for a carbonic acid shampoo to be effective. If there are other reasons for hair loss, carbonic acid will not help keep your hair from thinning or help it grow. Unfortunately, you will not know if DHT is the cause until you use a DHT blocker, like carbonic acid shampo.

Benefits Of Carbonic Acid Shampoo

Including carbonic acid shampoo in your hair care routine is an excellent way to cure aging, chemically treated or damaged hair and get beautiful, healthy hair. Some other advantages are:

  • Increase hair follicle blood circulation and heal damage.
  • It aids in the unclogging of hair pores.
  • Protect your hair from damage and enhance the texture of your hair.
  • Provide nourishment to the scalp while also assisting it in remaining clean and fresh.
  • Increase the volume and strength of your hair.
  • Enhance the overall appearance and feel of your hair.
  • Provide oxygen to the scalp.
  • Maintain hair moisture to keep it healthy and lustrous.
  • Reduce the amount of sebum produced.
  • Can prevent hair loss
  • It can help with dandruff.

How To Choose The Best Carbonic Acid Shampoo

There may be hundreds of carbonic acid shampoo options to choose from in the hair care aisle at your local drugstore or beauty store. So, which is the most effective? It’s difficult to pick a clear winner, but here are some pointers to help you pick the best shampoo.

Don’t Base Everything On The Price

Some individuals believe that more costly shampoos must be better. Why would it cost so much if it didn’t have to? Unfortunately, this isn’t always the case. While some pricey shampoos are incredibly effective, not all costly shampoos are. Don’t immediately go out and buy the most costly shampoo.

The Ingredients

Look for active ingredients like biotin, ketoconazole, rosemary, or collagen in the shampoo. You also want to ensure your shampoo is free from sulfate, paraben, phthalates, and silicone. If the active components aren’t singled out on the label, you can find them in the ingredient list on the back.

Try It Out

The only way to know for sure whether or not a shampoo will work for you is to test it. Most DHT-blocking shampoos are inexpensive, but many companies provide a 90-day money-back guarantee if you don’t notice results (though some specialists recommend using them for six months to see results).

How To Use Carbonic Acid Shampoo

Carbonic acid shampoos have the advantage of being able to be used in the same way as ordinary shampoo while yet being effective. Here are some more pointers on how to use this shampoo effectively:

  • The shampoo is often only in touch with the scalp for a brief period of time, which might diminish its efficacy. Before rinsing, try keeping the shampoo in for a few minutes.
  • Unless the label says otherwise, consider using the shampoo twice a day. If the label doesn’t say so, use it twice to ensure greater contact between the shampoo and your scalp.
  • It should not be used more than twice a day. While using the shampoo twice a day might be advantageous, doing it more frequently might be drying. When it comes to design, sometimes less is more.

For more effective results, you may want to consider doubling up on the carbonic acid intake. You can do this by taking a daily supplement which you can find at any local drugstore. Most of these supplements also have active ingredients that block DHT production, which will help to promote hair growth.

How Long Does It Take To See Results?

Seeing results can depend on how frequently you use the shampoo. Sometimes it can take a few weeks; other times, it can take a few months to see your hair start to grow. If you’re looking for results depending on the cleanliness of your scalp, you will see them almost immediately.
