The hair in the middle of your head might have a different texture due to natural genetic variations, where different hair follicles express genes differently, causing multiple textures (like waves, curls, or straight) on one scalp. Hormonal shifts, environmental factors (humidity, pollution), chemical treatments (coloring, heat styling), scalp health, aging, sleep position, and even certain medications can also contribute to these texture differences, making hair feel rougher, frizzier, or curlier in certain spots.
the texture of your hair is primarily determined by genetics and the shape of your hair follicles. if your parents have coarse hair, chances are, you will too. however, environmental factors also play a big role. exposure to harsh weather conditions, pollution, or chemicals can make your hair rougher and more brittle.
Signs of low porosity hair
Hair texture differences between sides may result from natural hair growth patterns, scalp health variations, or subtle environmental factors like sun exposure or sleeping position. Even with consistent shampoo use, underlying scalp conditions or uneven oil distribution can affect hair feel and appearance.
Over-moisturized hair looks limp, mushy, and lacks definition, with curls falling flat and feeling overly soft, stretchy (without bouncing back), and heavy, often appearing stringy or greasy, even feeling cool and damp for a long time after washing due to moisture overload and a lack of protein balance.
A simple test to tell if you're dealing with protein overload is to take a strand of your hair and stretch it. If it feels dry and brittle and snaps almost immediately, you've got a protein overload and you need to adjust your hair care routine accordingly.
The rarest hair type is generally considered Type 1A, which is extremely fine, straight, and wispy, lacking any natural bends or waves, making it difficult to hold a curl but naturally sleek and prone to oiliness. While curly hair types (Type 3 & 4) are less common globally, 1A stands out as the least voluminous and textured straight hair, often seen in people of East Asian descent, though it's considered rare across all populations due to its unique fineness.

You may develop coarse, dark hair growth on your upper lip, chin, chest, abdomen or back instead of the fine hair sometimes referred to as “peach fuzz” that commonly grows in those areas. Hirsutism can cause distress, but it's treatable.
Throughout life, thyroid hormones are essential for production of keratin. Low levels of thyroid hormones can cause dry and brittle hair. Oestrogen and androgens also regulate hair growth and loss, particularly as we age.
The other way to test is to simply run your fingers down a hair strand to feel its texture and hair porosity. If the hair feels smooth then it is low porosity, if it is rough or bumpy then it is high porosity.
Your hair is likely 2A if it has loose, subtle "S" waves starting mid-shaft, is flatter at the roots, and can easily look straight, while it's probably 2B if the "S" waves are more defined and prominent, starting lower down, with more body but still relatively flat at the crown, needing a bit more product to define than 2A. Think of 2A as "beachy," whereas 2B has more noticeable, elongated waves that can sometimes spiral.
Low porosity hair: The cuticles in low porosity hair are tightly packed together, this makes it difficult for moisture to enter the hair shaft. Due to this, pure coconut oil may not be beneficial to this porosity type.

Low levels of iron can often change the texture of your hair. It can go from feeling smooth and silky to dry and brittle. The main answer to this is that when you're low in iron, your body takes ferritin, a blood protein that contains iron, from your hair follicles for use in other parts of the body.
So, is frizz a sign of damage? The answer is yes and no. Frizz can occur in completely healthy hair, especially if it's naturally curly or wavy. However, when accompanied by other signs—like split ends, breakage, or lack of elasticity—could indicate underlying damage.
The "Big 3" hair loss treatments, popular in forums, are Minoxidil, Finasteride, and Ketoconazole shampoo, often combined to tackle hereditary hair loss (androgenetic alopecia) by boosting growth, blocking hormones, and reducing inflammation. Minoxidil (Rogaine) widens blood vessels, Finasteride (Propecia) blocks DHT, and Ketoconazole fights scalp fungus and inflammation, with microneedling sometimes considered a fourth addition.
In straight type, thin hair was judged most attractive, whereas in wavy type, hair with mean diameter received the highest attractiveness judgments. In conclusion, there was considerable variation in age, health and attractiveness perception of hair with regard to effects of hair diameter, type, and color.
