How Much Does Hair Weigh?

How Much Does Hair Weigh-

Have you tried to weigh yourself on the scale and wondered whether you’d weigh differently if you had short and thin versus long and thick hair?

Maybe its weight wouldn’t matter as much, but imagine: what if you really got it as long as Rapunzel’s?

People barely feel the weight of hair in daily life, but you can’t deny how your hair weighs a lot lighter after a drastic haircut.

It all just makes people want to know, how much does hair weigh?

How Much Does Hair Weigh: Facing Facts

Facing Facts

There’s a lot of ways and issues when we answer this question. How much hair weighs depends on several factors.

You also have to take into account the hair volume, type, and hair lengths. Note that your hair strands are not all in the same length too so they’ll also determine how much your hair weighs.

The Quick Answer

To give you a quick answer, a single 6-inch hair strand from the average person could weigh around 0.000076 to 0.00013 ounces.

A full human head of hair of that length would average around 6.1 and 13 ounces. Hair weighs more the longer it’ll be so you can expect it to be a little heavier if you have hair longer than 6 inches.

Does It Show on My Weighing Machine?

Unless your scale can measure up to several decimal spaces, no, the weight of your hair does not show on the weighing machine.

This means that cutting your locks won’t help you with your weight loss, and you can only try to change your body weight.

Factors That Affect Hair Weight


So what goes into those weight numbers? The human hair may look minute, but there are a lot of details that we can learn from its inner workings. Mainly, hair weight is affected by hair thickness and hair lengths.

Hair Anatomy

Hair is made up of a protein called keratin and dead skin cells. These are the same substances that make up our nails. To add, you can also find a small amount of sebum that came from the scalp and micro-amounts of minerals in each strand.

It is composed of three layers:


This is the outermost layer of hair. It protects the hair strand by encasing it in thick, overlapping scales. The cuticle is what you feel when you run your fingers through your hair.

A healthy cuticle is usually smooth with no damage to the scales. The quality of the cuticle varies with your race: Asians tend to have thick cuticles while Africans have thinner cuticles.


The cortex is the middle layer that contains the hair shaft. Your hair shaft grows from the root and gives body to the strand.

Here is where you can find your color pigments as well. These give you your hair color.


The innermost part of the strand is the medulla. It’s very thin and fragile that you would not be able to identify it with the naked eye when you cut your hair.

There is no significant purpose for this part, though it also holds color pigments.


If you follow your hair down to where it sprouts from the skin of the scalp, you won’t be able to see the bulb of the strand since it’s located at the bottom of the hair follicle from where hair grows.

While hair is mostly made up of dead skin cells, the bulb is very much alive. It is nourished by different nutrients that are delivered via small veins or capillaries in the hair follicle.

Phases of Hair Growth

Your hair length corresponds to one of three hair growth phases.


This is the growth phase where your hair continually grows in length for two to six years. Around 85% of your hairs are in this phase before they proceed to the next.


Known as the transitional phase, hair follicles start to contract, and hair growth declines. It happens in the span of a few weeks for around 3% of your current hairs in each hair follicle.


Hairs enter a resting phase where the old hairs fall out in preparation for the new one. It happens as the hair shaft detaches from the hair follicle, which is what happens with falling hair. This affects around 8% of your current hairs.

Hair Weight and Water

You’ll notice that as you step out of the shower, your hair becomes much heavier when it’s wet. This is because your hair can retain water for a certain period before the water dries up.

However, the added weight from the water on very long hair will only add a few ounces.

Increasing Hair Weight


The only way you can make hair weigh slightly heavier is to ensure that it grows as healthily as it can. This will improve the hair quality and make sure the hair cuticle is undamaged.

Hair Nutrients

Your hair needs nourishment so that the cells in the hair bulb can continue to produce hairs. You must simply eat a well-balanced diet that contains omegas-3 and 6.

You can further improve this with hair supplements that you can find in the local pharmacy. Try them out first to see if the formulation suits you and no unwanted side effects appear.

If those aren’t as effective as quickly as you’d like, you might want to try out some lace wigs in the meantime.

Coconut Oil

Your hair can also improve with the help of essential oils. A good choice is to use coconut oil. There are many ways to use the oil, like a hair mask or a pre-wash protector.

The most common method is to work the oil into the hair and let it sit overnight. This will protect your hair by keeping in moisture and preventing breakage.

Be careful not to put too much oil, or else it can cause too much buildup and irritate your hair.

You can also get a hair treatment at the salon instead, where salon experts can use various fragrant oils. A coconut oil hair treatment will surely revive your hair.

Other people also like to use Olive oil as a substitute. It has pretty much the same properties as Coconut oil, minus the strong scent.

Hair Fun Facts

Fun Facts

#1 Who has the longest set of hair?

The Guinness World Record holder for the longest hair would belong to Xie Qiuping from China. Her hair was measured at 18 feet and 5.54 inches when it was last measured in 2004.

She’s been growing her hair since 1973 when she was just 13 years of age. How crazy is that?

Imagine how heavy her hair would weigh with wet hair! Wet hair is heavier than dry hair because of the water content, so just imagine trying to manage that.

A normal person would get neck pain over time unless a friend helps carry the weight eventually. And she’ll even have more difficult showers because wet hair is heavier!

#2 How much hair loss is considered normal before it becomes a problem?

As some of your hair enters telogen, you can expect to lose around 100 strands per day. It may seem a lot, but you may not notice how much hair falls as you brush your hair or when you tie it up.

Don’t worry about it too much! Most of your hair is constantly growing in the anagen phase, so keep your hair healthy, and your stress levels low if you want to retain fuller head hair.

Men tend to have a problem with it since they are more susceptible to increased hair fall. Yet, women can also lose hair, especially when it’s hereditary.

#3 How can I grow more hair?

Unfortunately, you are born with a set amount of hair follicles, so the number of strands you can have at a time is set. This is because you don’t grow more hair follicles as you grow older.

You can still get long hair, no matter how many hair follicles you have though. So if length is your issue, then no need to worry much.

#4 How strong can hair get?

Human hair is so light and easy to cut with scissors. But did you know that hair is strong enough to pull things that are as heavy as a car? 

That’s why some hair types might require hair clippers instead of just plain scissors.

The secret of hair strength lies in the keratin. It’s a very durable and sturdy substance. You can imagine better when you realize that keratin also makes up a rhino’s horns.

A full human head of long hair, when used right, can pull up to 20,000 pounds. Something like that is equivalent to two African elephants!

Final Thoughts

Final Thoughts

To solve your question of how much does your hair weigh, many factors affect the average weight of our hair, and it would be difficult to come up with an accurate number for the weight of our own.

Still, we can change the weight of your hair, albeit with little difference on the scale. It’s still possible as we discover the factors that affect how heavy does hair weigh. This includes your hair thickness and hair length.

And suppose you intend on making your hair weight a bit heavier. In that case, you only need to nourish the strands to add weight. Do this by either consuming enough nutrients to promote hair growth or keeping it free from damage by using essential oils.

So, have you ever tried to weigh your hair?
