The Best Shampoo to Thicken Hair in 2021

Men’s hair is not the same as the women’s hair. Women’s hair looks good even when they have thin strands, which cannot be considered a very good quality for the hair of men.

So, men and women might require a different shampoo to address their hair fall issues. However, some shampoos can help both men and women and allow their hair to look thicker and fuller by working directly on the hair strands.

These are called the hair thickening shampoos. Before you get to lay your hands on the best shampoo to thicken hair, wouldn’t it be wise to have your basics cleared? Let’s begin with the understanding of hair thickening shampoo.

Most men and women are born with thin and fine hair while others find their hair thinning as their age advances

While hair loss is normal and a natural process, anyone would enjoy and prefer having his or her head covered with thicker and fuller hair as long as possible.

I would like to clear some doubts you may have about these shampoos and share the information about how to use the best shampoo to thicken hair and why are they so useful.

Best Shampoo to Thicken Hair

1 – Avalon Organics Biotin-B Complex Thickening Shampoo

Avalon Organics Biotin-B Complex Thickening Shampoo

My hair is a bit spread across the entire scalp. I mean I don’t have patches of baldness. So, my scalp is easily visible through the hair.

Hence, I was mainly concerned about the interaction this shampoo will have with my skin.

Since my scalp is sensitive, I was also worried about allergies and irritation of the scalp. My scalp usually gets irritated by the typical commercial shampoos.

But, I was quite satisfied with this shampoo. No irritation, no allergies, and no itching. I think the main factor that worked for me was this shampoo is made from natural ingredients and does not have too many harsh chemicals.

You name any hair-healthy herb, and it is present in this shampoo starting from Aloe Barbadensis and Xanthan Gum, to Avena Sativa and Calendula Officinalis.

I had good results with this shampoo and would recommend it for those with a sensitive scalp.


  • Natural and organic
  • Improves the hair growth
  • Smells good
  • No itching, or irritation of the scalp
  • It claims to be a vegan and biodegradable product (I suppose that’s a plus point for the naturalists)
  • No harsh sulfates or preservatives


  • Not suitable for dry hair or scalp
  • Contains biotic (so, not suitable for those with biotin allergy)

2 – Amazology RAINFOREST Argan Oil Thickening Shampoo

Amazology RAINFOREST Argan Oil Thickening Shampoo

This one’s another hair thinning shampoo with great results. I could see the difference in my hair within first 3-4 washes.

Actually, I didn’t want to try any other product after this. The reason I continued with my research was my greed of finding something better than this!

I am impressed with its ingredients. It has Açaí Oil, which, as per the best of my knowledge, is a powerful antioxidant.

To make it simpler for you, it prevents the destruction of cells and hair follicles that can lead to hair loss or thinning.

What’s more, it also has Green Tea Leaf Extract, vitamin E, Passion Flower Seed Oil, Cupuaçu Butter, and many other ingredients, which really are worthy for our hair.

I would give a great thumbs-up for this product. After I completed my research, I switched back to this product and have been using it since then.


  • Greta combination of natural ingredients
  • Faster results
  • Easy on the scalp
  • Suitable for a dry scalp
  • Contains vitamin E (so, you can say it’s nourishing for your hair)
  • Didn’t leave any oily residue after washing
  • Hair is better manageable since there is no residue


  • The smell is a bit strange (though I won’t call it bad or nauseating)

3 – Polyactiv Green Apple Complex for Thickening Hair Growth and Restoration

Polyactiv Green Apple Complex for Thickening Hair Growth and Restoration

I wouldn’t call this shampoo a great one; but it’s definitely much better than most of the so-called natural and herbal shampoos available in the market.

The results were good, my hair fall reduced considerably. But, there was no drastic change. Plus, it took a longer time to show results than the other shampoos.

The plus points include it contains Jojoba leaf, Rosemary, Sage, Grape Seed, Aloe Vera, and more!

Rosemary is as effective as Minoxidil, a common chemical used in most hair care products and Proanthocyanidins in grape seeds promote the proliferation of hair follicle cells and improve the hair growth.


  • No harsh chemicals
  • Smells fantastic
  • Doesn’t dry up the scalp


  • Results are too slow (you need to hold on to your patience)

4 – Bumble and Bumble Shampoo – Thickening

Bumble and Bumble Shampoo

I had a hard time laying my hands on the original Bumble and Bumble Shampoo; but once I tried it, I simply loved it!

I could see the difference within a few weeks. My hair was thicker and the scalp was not as visible through the hair as it was previously.

My hair also became soft and shiny.

So, I would say it’s a good product provided you manage to get the real one.

The list of ingredients is impressive: it has panthenol, wheat protein, and Aloe vera. Based on my research, I can tell you that wheat protein could be behind the successful results I got.

Beware! If you are purchasing this product online, there are chances you would be delivered a fake product. This is the most common issue with this product and you will find many reviews to this effect.


  • Impressive results
  • Improves the texture and appearance of hair
  • Smells nice
  • No itching or irritation


  • Hard to find a genuine Bumble and Bumble Shampoo online. If possible, try to purchase it from your salon

What is a Hair Thickening Shampoo?

how to use rogaine

Do you know that a hair thickening shampoo is different from the regular shampoos we have been using for so long?

I am sure, like me, even you thought that the hair thickening shampoos are just like any other shampoo that conditions your hair and makes them appear shiny and attractive.

So, to begin with, let me tell you that a hair thickening shampoo, also called a hair volumizing shampoo, is not like any other normal shampoo.

It actually thickens your hair strands temporarily by causing them to swell, which means if you have about 100,000 hair strands on your scalp, then your crown will appear a bit voluminous after using these shampoos as each hair strand will become thicker than its normal size.

One point I would like to stress again that this effect is temporary as these shampoos work artificially to swell the hair shaft by depositing a thin film of its active ingredients on your hair strands.
So, these shampoos tend to create a buildup of residue if you use them daily and this buildup then requires a stronger clarifying shampoo to have it removed.

How to Use a Hair Thickening Shampoo?
Since a hair thickening shampoo is different from your usual shampoo, its method of using is also a bit different. While you may apply it like a normal shampoo, the frequency of its use should be lower to minimize the risk of residue accumulating on the hair strands.

I would recommend using a hair thickening shampoo about 50% less frequently than your regular shampoo
Another way to flaunt thick hair while keeping the damages caused by these shampoos to the minimum is to reserve its use only for certain occasions when you want to enhance the volume of your hair.

Why Should You Use a Hair Thickening Shampoo?

There are many benefits of using a hair thickening shampoo. I have listed a few of them just to highlight its importance.


This one’s pretty much self-explanatory! Your hair will look fuller and healthier


Some of these shampoos provide extra nourishment to your hair as they are added with some powerful hair nourishing herbs. So, it works like a “two birds-one stone” effect for you.

Such types of hair thickening shampoos feed your follicles with a few extra nutrients and make your hair healthier in the process.


Yes, you guessed it right!!!

The hair thickening shampoos will, obviously, thicken your hair and expand their diameter.

This effect, when multiplied over the entire scalp, changes your appearance drastically, especially if the thinning has just started out and you still have plenty of hair covering your scalp.

It might also help those who are on their last leg of baldness to achieve the appearance of thicker hair.


A hair thickening shampoo provides you the freedom to use it as per your wish. In fact, it works great for on and off use and allows you to have thicker hair whenever YOU want.


Though hair thickening shampoos do not cure male pattern baldness, they might help to fight the unattractive looks caused by it to some extent.

Hair thickening shampoos can be used to create an illusion of having more hair and thus, tame the effect of hair loss caused by male pattern baldness.

Well… But…

I must caution you that it will not help to regrow your lost hair or revert the balding process. A hair thickening shampoos can merely help in defeating the visually-manifested hair loss, that too temporarily.

Do Thickening Shampoos Actually Work?

You might think, why you should use a hair thickening shampoo when the effect is just temporary. Your concern is justifiable. But, I must say that even with this seeming disadvantage, they do are popular simply because of the visibly noticeable effect it produces.

And why not? Don’t the Hollywood celebrities don layers of makeup only to wash it off after the event is over? Even the effect of that makeup is temporary.

So, I don’t see any harm in trying to look desirable, even if it’s for a short duration, by using these shampoos.

Well… As far as how good they work, the answer can be summed up in one word and that’s “remarkable”. Though it’s not going to be a difference between night and day, it will be visibly noticeable.

The results vary from person to person depending upon the type of hair and the stage of hair loss he is experiencing.

Any Word of Advice?

People with some specific hair types need to be more careful while using hair thickening shampoos.

If you have curly or wavy hair, then these shampoos might give you a haystack look.

If that’s what you are looking for, then it’s mission accomplished! Otherwise, steer clear of these shampoos. A safer option would be to do a test run on any of your off days instead of trying it out for the first time on “THE’ day!

There are several hair thickening shampoos for men, and almost each of them claims to be the best shampoo for hair growth

To get the facts rights, I decided to use each for a period of a few months so that I could decide for myself which one was actually the best hair thickening shampoo for men.

Based on my experience and some research, I have finally shortlisted 4 of them that really worked for me.

So, what’s my favorite?

Of course, Amazology RAINFOREST Argan Oil Thickening Shampoo. It suits my hair really well. And any shampoo that suits my hair can suit everyone else’s hair because I believe I have got the worst hair and scalp in this world (just kidding :D)

It’s mild and gentle. It has natural ingredients. It is also soothing for my scalp. And the best benefit is it reduced my hair thinning within just a few weeks. I no longer belong to the “hair-thinning” category.

Hope you found out your favorite once and got some valuable information, share with your friends and let’s beautiful hair rule the world! I will see you in another article.​
