Comparison to Body Weight: Despite the sensation of weight in your hair, its actual weight is incredibly light when compared to the overall weight of your entire body. The average human head of hair, which can weigh anywhere from 100 to 150 grams, represents only a fraction of the total body weight.
The weight of all the hair on an adult human can vary significantly based on factors such as hair type, density, and length. However, a rough estimate is that the total weight of hair on an average adult human ranges from about 100 to 200 grams (approximately 3.5 to 7 ounces).
Various sources on the Internet say that a full head of long hair weighs somewhere from an ounce or two (30–60 grams), which might be correct, to 5 pounds or so (2.5 kg), which seems far too high an estimate (your hair doesn't weigh as much as a pair of roller skates, or 2 1/2 liters of water).
All in all normal hair density is somewhere between 170-220 hairs per sq cm ( ... or roughly 80 follicular units to 120- follicular units per sq cm). The back is more dense than the temples. The highest density occurs at birth and then slow reduces as the individual gets older. How do you make hair more dense?
A single strand of human hair has the potential to support around 100 grams of weight. That is the same as an average bar of soap, found in the bathrooms of many homes.
You'll need a lot more volume products when your hair is long. Mousses and foams are your best friend, especially at your roots, which get weighed down by the heaviness of the hair.
That's how far you can stretch it before it breaks, and it's measured in megapascals (MPa). Human hair is in the neighborhood of 200 MPa, while structural steel is about 400 MPa. Spider webs are far stronger, though, at 1,200 MPa. And carbon nanotubes are among the strongest known materials, at about 62,000 MPa.
Due to the implantation, hair also does not grow at the same rate. Asian hair grows the fastest, approximately 1.4 cm per month, Caucasian hair grows 1.2 cm, and African hair grows 0.9 cm due to its spiral structure.
Estrogen is very good for the hair. After menopause, women lose estrogen and hair.” It's normal to lose 50 to 150 hairs per day. That may seem like a lot, but most people have about 100,000 hairs on their heads at any given time.
Apart from regular grooming, a Domestic Longhair has the same needs as any cat breed, including plenty of human companionship, mental as well as physical enrichment, and a healthy, balanced diet. The weight range for the Longhair is between 10-22 pounds, and life expectation is anything from 12 to 20 years.
In the tragic story of Absalom, the handsome son of King Solomon, his scalp hairs used to get so heavy that he had to often cut them, and it was found to weigh 200 shekels by the royal measure, which is about 5 pounds - quite a weight to be carrying around on one's head.
Estimates for the number falling out range from 50 a day to 500 a day. Like I know human hair can support 100 grams and theoretically a full head of hair could support 12,000-18,000 pounds.
Longs: These dreadlocks weigh about 13-16oz and provide a more dramatic, fuller appearance. They are great for those who are comfortable with the weight and ready to make a bold statement! Many women enjoy alternating between Shorties and Longs based on their lifestyle or personal preferences.

Over time, hair fibers become thinner and drop out, and unfortunately, they never regenerate. Natural pigment (color) changes occur in hair as you age as well. Pigment cells stop producing as much, and eventually, your once thick, chestnut hair becomes thin, fine and gray.
Chinese men were less likely than White men to experience balding in any pattern. Black participants also had lower odds for temporal, vertex, and severe balding but to a lesser extent than Chinese men.
Asian hair
Because of its extra diameter, it is also the strongest, and most resistant to damage. It is normally straight or only lightly wavy with a good amount of volume, because of its thicker diameter, even though there are typically less hairs per head (around 500,000).
Type 1A is the rarest hair type and is stick-straight without even a hint of a wave.
To their surprise, they found thin hair was able to endure greater tension before it broke compared to thick hair. This also applied to hairs from the same species. For example, thin hair from a child was stronger than thicker hair from an adult.
The cuticle is the hair's outer most layer which has shingle or scale like cells that overlap. These cells work defensively to prevent damage to the hair's inner structure and to control water content of hair fiber. The middle structure includes the cortex which provides strength, color and texture of the hair.
