Baking Soda Shampoo: Does It Really Help Hair Grow?
Baking Soda Shampoo: Does It Really Help Hair Grow?
Baking soda has become a popular ingredient in DIY beauty routines, including homemade hair cleansers. Some people claim that replacing regular shampoo with baking soda can make hair grow faster, remove buildup, and even prevent hair loss.
But does it actually work?
Not for hair growth. There is no good evidence that baking soda shampoo stimulates hair follicles or makes hair grow faster. In fact, using baking soda directly on your hair and scalp—especially every day—can be irritating and may leave hair feeling dry or damaged.
If you're interested in a simpler hair-care routine, there are safer ways to keep your scalp and hair clean without relying on a harsh DIY shampoo.
Can Baking Soda Make Your Hair Grow?
This is the biggest claim made by many DIY baking soda recipes, but it isn't supported by good evidence.
Hair growth depends on what is happening inside the hair follicle. Hair loss can have many different causes, including hereditary hair loss, hormonal changes, certain medical conditions, nutritional deficiencies, stress, and damaging hair-care practices.
Changing your shampoo cannot fix every cause of hair loss.
The American Academy of Dermatology recommends finding the underlying cause when you're experiencing noticeable hair loss because treatment depends on the cause.
So, baking soda is not a proven hair-growth treatment.
Why Do Some People Think Baking Soda Works?
Baking soda can remove oil and buildup from surfaces, so hair may temporarily feel very clean after using it.
That clean feeling can make a DIY treatment seem effective.
But there's an important difference between removing buildup and stimulating hair growth.
A product can make hair feel cleaner without changing how quickly your follicles produce new hair.
Is Baking Soda Safe to Use as Shampoo?
Using a small amount occasionally isn't necessarily going to cause a problem for everyone, but baking soda isn't a good replacement for a properly formulated shampoo—especially as a daily routine.
Your scalp has a natural protective environment, and harsh or irritating hair-care practices can contribute to dryness and damage.
Dermatologists generally recommend choosing hair-care products appropriate for your hair type and using gentle washing techniques.
If baking soda makes your scalp feel:
dry
itchy
burning
tight
irritated
stop using it.
There is no reason to continue a DIY treatment that is making your scalp uncomfortable.
What About the Baking Soda + Vinegar Method?
The original recipe recommends washing with baking soda and then rinsing the hair with diluted vinegar.
This combination is often promoted online as a natural alternative to shampoo and conditioner.
However, there is no good evidence that this routine promotes hair growth or prevents baldness.
It is also unnecessary to use an acidic vinegar rinse simply because you have used baking soda.
If you want healthier-looking hair, a properly formulated shampoo and conditioner designed for your hair type is a more practical choice.
Do Regular Shampoos Cause Hair Loss?
The original article claimed that modern shampoos contain thousands of harmful chemicals and can cause thinning and baldness.
That is far too broad.
Shampoos contain multiple ingredients, and different products have different formulations. Some hair products can cause irritation or damage in certain people, and the FDA has received reports of adverse reactions associated with some hair-cleansing products. However, that does not mean ordinary shampoo generally causes baldness.
Hair loss has many possible causes, and the right approach is to identify the cause rather than blame all commercial shampoos.
A Better Way to Wash Your Hair
You don't need an unusual homemade recipe to take good care of your hair.
Dermatologists recommend a few simple habits.
1. Choose a shampoo for your hair type
Hair can be straight, curly, coarse, fine, dry, oily, or somewhere in between.
Choose products designed for your hair and scalp rather than assuming one DIY recipe works for everyone.
2. Apply shampoo mainly to your scalp
The American Academy of Dermatology recommends applying shampoo to the scalp rather than aggressively rubbing it through the entire length of the hair.
This helps remove excess oil, buildup, and dead skin while reducing unnecessary drying of the hair shaft.
3. Use conditioner after washing
Conditioner can help moisturize and detangle hair and reduce breakage.
If your hair is fine or straight, you may prefer applying conditioner mainly to the ends. If your hair is dry or curly, applying it more broadly may work better.
4. Be gentle with wet hair
Wet hair is more fragile.
Avoid aggressive brushing or pulling. A wide-tooth comb can be useful for gently detangling wet hair, depending on your hair type.
5. Limit damaging treatments
Frequent chemical treatments, excessive heat, and hairstyles that constantly pull on the scalp can contribute to hair damage and, in some cases, hair loss.
Reducing these sources of damage can help protect the hair you already have.

What If Your Hair Is Actually Thinning?
If you're noticing a widening part, receding hairline, bald spots, or significantly more shedding than usual, don't rely on baking soda or another DIY remedy to solve the problem.
Hair loss can result from many different causes, including:
hereditary hair loss
hormonal changes
thyroid problems
certain nutritional deficiencies
illness or major stress
autoimmune conditions
damaging hairstyles
chemical or physical hair damage
The American Academy of Dermatology notes that identifying the cause is an important first step because treatment depends on what's causing the hair loss.
What About "Natural" Hair Treatments?
Natural doesn't automatically mean safer or more effective.
Baking soda, vinegar, essential oils, and other kitchen ingredients can sound appealing because they're inexpensive and familiar. But your scalp and hair aren't the same as a kitchen surface.
Before putting a DIY ingredient on your scalp, consider whether there is actually evidence that it provides the claimed benefit—and whether it could cause irritation or damage.
A simple routine that works well for your hair type is often better than constantly switching between viral DIY treatments.
Can Baking Soda Remove Product Buildup?
Baking soda can have cleansing properties, which is one reason it appears in some homemade hair and dry-shampoo recipes.
However, the American Academy of Dermatology specifically cautions that homemade dry-shampoo products containing ingredients such as baking soda can clump and potentially irritate the scalp.
If you regularly use styling products and feel that your hair has buildup, choose a commercially formulated product appropriate for your hair and scalp instead of assuming baking soda is the best solution.
Frequently Asked Questions
Does baking soda make hair grow faster?
No. There is no good evidence that baking soda stimulates hair follicles or makes hair grow faster.
Can baking soda stop hair loss?
No. Hair loss has many possible causes, and baking soda is not an established treatment for hair loss.
Can I use baking soda shampoo every day?
It's not recommended as a daily hair-washing routine. Repeated exposure may leave some people's hair or scalp dry or irritated.
Is vinegar good for hair?
Vinegar is sometimes used in DIY hair rinses, but there isn't good evidence that a baking soda-and-vinegar routine promotes hair growth. If a product or ingredient irritates your scalp, stop using it.
What is better than baking soda for everyday hair care?
A gentle shampoo suited to your hair and scalp, followed by appropriate conditioning, is a more reliable everyday approach.
Does shampoo cause baldness?
Ordinary shampoo should not automatically be blamed for baldness. Hair loss has many causes, and noticeable thinning or shedding should be evaluated based on the individual's situation.
The Bottom Line
Baking soda may sound like a simple, natural alternative to shampoo, but there's no good evidence that it makes hair grow faster or prevents baldness.
Using it occasionally may not cause a problem for everyone, but making a concentrated baking-soda mixture and using it every day is not a proven way to improve hair growth—and it can leave some hair or scalps dry and irritated.
For healthier hair, focus on gentle washing, appropriate conditioning, minimizing damage, and choosing products that suit your hair type.
And if you're experiencing genuine hair loss, don't spend months trying DIY remedies. Finding the cause is much more important than finding a "magic" shampoo.
