Hair with low porosity is much harder to process and is very resistant to hair color because the cuticle is tight and difficult to open up.
Straight – hard to damage and tricky to curl – this is the oiliest and most resilient of all hair types.
Fine hair is the most fragile hair texture. Each individual hair is thin and only has two hair layers; cortex and cuticle. If you have this hair type, you might find it hard to keep your hair in a style, or it might get oily easily.
We believe one of the reasons is that super-straight hair — also known as type 1a hair — is so rare. In fact, it's the rarest hair type. Only 2% of the world's population has 1a hair. It's mostly found in people of Asian descent.
The least common hair type, 1A hair is extremely fine and perfectly straight. Consequently, it can look a bit flat and limp and might prove difficult to style. Dry shampoo can be your ally in the fight against excessive oil and thick hair products that might weigh your hair down are best avoided.
Fine Hair. Fine hair is typically very soft and delicate. Made up of only two hair layers (the cortex and the cuticle), these hairs can be silky smooth and sleek, but they're also the most prone to breakage.
Thick or coarse hair is the thickest and most resistant to damage. It has all three layers of hair: the cortex, cuticle, and medulla. Thick hair has the appearance of a full head of hair and can hold styles well. However, it may take longer to dry and can become frizzy in humid weather.
Less than 20% of people have naturally curly hair.
Thicker strands of hair are more likely to have a defect, making them more prone to breakage, the researchers believe. Lustrous, thick hair may be desirable but it is not necessarily the strongest. Scientists said thin hair tends to be stronger than thicker locks, after looking at the way they break.
Asian hair is also the fastest growing, at over half an inch per month. Caucasian hair can be stick straight, wavy, or curly. The follicles have a slight oval shape, making it quite dense with an average hair growth of just under half an inch a month.
Avoid Pulling Wet Hair Back into a Ponytail or a Bun
"When you tie your hair back it stretches up to a third of its length causing tension breakage," says Rob. “So make sure it's pretty dry before putting it up.
It is best to sleep with your hair down if your hair length is short. This also lets the air flow freely through your hair, which makes you sleep more comfortably. On the other hand, if you have long hair, it is recommended to tie your hair loosely to prevent knots and breakage.
Type 1 hair is hair that lies flat, or straight. Straight locks tend to be on the shinier side because the hair's natural oils are able to travel from root to tip. This hair category includes divisions 1A, 1B, and 1C. Type 1A is “stick” straight hair that has no hint of curl or wave.
Coily Curls
The last, but most rare type of curl is the coily curl. This curl type is similar to that of an afro and when observed carefully, looks like the angular letter 'Z'. These curls require the most amount of moisture, as the hair type is much thicker than the other curl types.
Most women think brunette hair is the sexiest, as 25% of those polled favoured this option. Womens' second preference is blonde, which was voted as the sexiest hair colour by 19.6% of women. Again, red took third spot, accounting for 11.8% of womens' votes.
In the present study blondes were not preferred by either sex: a clear preference for brunette hair coloration over blondes and redheads was indicated. In concurrence with both earlier studies, the results of this study indicated red hair as the least preferred hair color.
There's presently no indication that mold can develop on human hair. However, your hair probably smells moldy due to other fungal infections, such as seborrheic dermatitis or Malassezia yeast. These fungal infections can cause your scalp to look and feel greasy, itchy, and irritated.
When to wash. Rossi generally tells his patients they should wash their hair once or twice per week. But if you've had chemical treatments that can make your hair drier — such as bleach, perms or relaxers — you might want to wash it less than once weekly to avoid breaking or brittle hair or split ends, he said.
1. Pulling hair too tightly. Protective buns, puffs, and ponytails can be good ways to keep hair out of your face, but they are also a major source of thinning edges. Tight hair styles can add stress to hair follicles, causing hair breakage.
Pubic hair may extend out to their thighs, and some girls may have a line of hair up to their belly button. Most girls attain their peak height by age 16, but some may continue growing through age 20.
Asian hair shows the fastest growth rate in comparison to the other two hair types. African hair has the lowest growth rate. Hair growth rate and hair diameter were reported to be associated with cuticle interscale distance.
Factors that influence hair growth
Genetics: A person's genes will dictate how quickly their hair will grow. Sex: Male hair grows faster than female hair. Age: Hair grows fastest between the ages of 15 and 30, before slowing down.
