If curly hair is genetic why do you have curly hair if none of your ancestors did?


Answer


The answer to your question may lie in the way that hair-type genes are inherited. 
First, a review of some basic genetics stuff. For most genes, you have two copies of each gene that you inherited from your mother and father. For most "traditional" genes, there is a dominant and recessive version. This all has to do with gene expression and phenotype, or what you actually end up looking like. If at least one dominant version of the gene is present, it will be expressed regardless of what the other is. The only way the recessive version will be expressed is if the dominant version isn't present. This holds true for some simple traits like whether earlobes are attached or not, where the free earlobe allele is dominant (noted as "E") and the attached (noted as "e")allele is recessive. So if at least one of your parents had free earlobes (Ee or EE), you'll have free earlobes. EDIT: if both you're parent have free ear lobes you can still get attached ear lobes in the case that there heterozygous dominate. because if both parent are Ee then you have 1/4 chance of getting ee.
So why don't you see your hair-type in your parents or grandparents? Well, hair-type doesn't follow the nice and simple pattern of inheritance. Hair-type follows a type of inheritance pattern known as "incomplete dominance". Like the earlobe gene, there are two versions of the hair-type gene, curly (noted as C) and straight (noted as s). The incomplete dominance refers to the fact that if you have one of each version of the gene, you get a mix of the two or, in this case, wavy hair. So for hair type, CC gives curly, Cs gives wavy and ss gives straight hair. 
Without a better family history, all I can tell you is that it is possible that the curly version of the gene was carried by both of you parents as "Cs", or wavy-type. The same could also be true of your parents parents, but beyond that it gets really unlikely that "none of your ancestors" had curly-type hair. Of course, it's also possible that your curly hair might actually be wavy, or wavy-type. Outside the world of genes, wavy and curly are really just in the eye of the beholder.  

Answer

I will start with saying, I myself have been cursed with curly hair. I have found that it seems like if you are female, you usually pick up the same/similar type of hair of your paternal grandmother. I don't know that this is proven anywhere, but with my family this is what shows true. All of my female cousins that were born to my father's brothers all have curly hair. And my female cousins that have straight hair were born to my aunts. Seems weird, but holds true in my situation. That's all I have to offer.  

Answer

Somewhere along the line one of your family members has curly hair. I look white. But I had a tumor removed 3 years ago and it is only common in black women. Well through research I have found out that my great-grandma is black:)  

Answer

Genetics in families goes back 100s of years, and you could be what they call a "throw-back." Simply meaning that a gene from a great-great-great grandfather/grandmother could well be in you. My husband comes from a family of 5 kids. He is the only one that is over 6 feet (6' 6" tall) with olive complextion and light blue eyes and a cleft in his chin. It always bothered him he looked so different from his other siblings. One day his aunt gave him a picture of his grandmother when she was very young and she was 6 feet, size 19" waist, light blue eyes and that cleft in her chin. He was rather proud of the whole fact. I am sure most of us have a lot of different races in our families if we research enough. I have Spanish and Indian in me, but it goes back some 350 years ago.

ANSWER. 

While some regard curly hair on the head as a "mutation" and straight hair as the "norm" a deeper look might suggest that the opposite is the truth. 

Humans are believed to have originated in Africa, and to have spread from there to the rest of the world. If one looks at a typical African native one will see a person with tightly curled black hair, in a typical "Afro" style (if left to grow naturally). 

It is suggested this type of hair, black, tightly curled, and "bouffant" is a result of natural selection, which is due to at least 3 reasons, though the weight given to each reason is open to argument. 

1. Black hair is good at absorbing Ultra-violet, thus helping to prevent skin cancer on the scalp. 

2. The tight almost "brillo pad" effect is good at keeping sun light off the head, to prevent overheating. 

3. The natural "weave" of the hair is open, allowing air to circulate, aiding cooling. 

It is then further suggested that as these "proto-humans" left Africa and colonised the rest of the world the above 3 reasons to have black, tightly curled hair actually became a disadvantage. 

1. The UV levels fell, as did the average temperature. Clothing was worn to keep warm. Humans need UV exposure to produce Vitamin-D. Those with a less protective hair type were better able to produce vitamin-D. There are also theories (unproven) that blond straight hair hanging down is favoured in cold countries at it has a "fibre optic" effect, catching sun-light reflectied off the snow, and feeding it to the scalp. 

2. The "heating" effect of the sun was reduced, less need for "solar insulation." 

3. The colder climate favoured a hair type that insulated the head from the cold, rather than allowed active cooling, as most heat is lost from the head. 

Hence, having straight hair is actually the "mutation," and having curly hair is normal, so at some point ALL of your ancestors had curly hair, afro Style.

Hair Tells each and everything about your health and your Health related Issues.

We’ve got a handle on how to style, moisturize, co-wash, deep condition, twist out, braid out, big chop and transition our hair. Great. While everyone has spent the last few years becoming experts on their hair (and everyone else’s for that matter), one topic that is not being widely addressed across the blogosphere is how directly related the health of our hair is actually related to our overall health. Sometimes it’s not just about getting the best shea butter product on the market or experimenting in the kitchen with beauty food. Our deepest hair issues and concerns can often lie primarily in what is going on internally. Before we begin dressing up our hair concerns with product and remedies here are a few health-related hair issues that may require a call to our doctor:

 Hair Loss and Polycystic Ovarian Syndrome– I shared my PCOS story with you all when I first began writing this blog. This hormonal disorder affects more than five million women nationally affecting fertility, weight and hair growth. Women with PCOS typically produce unusually high levels of androgens (male hormones) which can cause a condition called androgenetic alopecia. This typically causes hair at the scalp to become thin and fall out. There are a variety of treatments for this type of hair loss involving birth control pills, medicines and even growth stimulants but it’s best that you speak with your doctor about what treatments are best for you.  See also 9 causes of hair loss in women.

Dry Hair and Underactive Thyroid – Sometimes having even the best moisturizing hair care system in place just doesn’t cut it. When our thyroid gland does not produce enough produce enough of the thyroid hormone (also known as hypothyroidism), among a host of health-related issues, our hair, skin and nails can become dry, brittle and weak. Even our eyebrows can start to thin. It’s important that you check in with your doctor to find out if your dry hair issues are attributed to hypothyroidism. See also 13 ways you can treat it naturally.

Hair That Won’t Grow and Malnutrition – Our hair needs plenty of healthy vitamins and minerals to grow and stay healthy including lots of proteins, omega-3s, zinc and vitamin A. When our bodies are lacking in these important nutrients it can cause our hair’s growth to be stunted and even fall out. Malnutrition isn’t anything to play with especially when a main cause could be an eating disorder. It may be beneficial to meet with a dietitian or holistic nutritionist to determine what you may be lacking in your diet and how a meal plan may help you regain control over your hair’s health.

CURLY HAIR ISSUES AND HOW TO STYLE CURLS ON CURLY HAIR



In the past few months, my curly hair has been growing in straight. Could this be due to the new dye my colorist is using—or is it my fluctuating hormones?


It's probably not the dye that's changing your hair texture, says David H. Kingsley, PhD, author of The Hair-Loss Cure: A Self-Help Guide. But hormonal shifts—like those that occur during puberty, pregnancy, and menopause—can alter the shape of the hair follicle. (Think of the follicle as a tube: If it has a slight curve, the hair grows in curly; if it doesn't, the hair grows in straight.) Hormonal changes can also affect the diameter of the hair, making it coarser or finer. 


Keep in mind: As your texture changes, consider switching shampoo and conditioner, says hairstylist Ryan Trygstad of the Marie Robinson Salon. If you had thick, curly hair that's now growing in straighter and finer, you'll have better hair days if you choose lighter products formulated for your new type. (Try Pantene Pro-V Fine Hair Solutions Flat to Volume Shampoo, $5, or Dove Volume Boost Conditioner, $4, drugstores.)

Earlier this summer we wrote about how sometimes long hair, especially if it is a little wild, can be perceived as unprofessional. One of the people interviewed for that story, workplace.Alexandra F. Figueredo, said when she worked in banking she kept her naturally curly hair slicked back, because she thought it looked more professional. But do curls, even if they are very well-kept, come off as unprofessional? We talked to some women about this.
Jessica Kupferman told The Grindstone:
“I have had curly hair all my life and I can tell you, many of us curly haired gals straighten when we go on a job interview so we don’t seem too “crazy” or wild-minded. I know I often do. In my more corporate days, when I wanted to be taken really seriously, I would straighten my hair – and it was much longer and took me an hour. I’m not sure WHY there’s that mindset – almost as if curls are created by some insanity brainwaves and therefore can’t be trusted – but even women with curly hair will tell you, we act accordingly. And men never seem to have this problem. I’ve never met a man interested in straightening his hair, ever.”
Courtney Huber, a communications specialist, told The Grindstone:
“I have very curly hair, and I try to own that about myself. Most of the time I let it flow in loose curls. It’s possible to wear it curly yet still with a professional look – up in a twist with curls loose at the top, or pulled back at the sides. Although I think the real issue is, who says “professional” has to mean straight? I think that is just a construct that Americans have perpetuated for unknown reasons. We don’t have to follow it.
I say embrace it. Maybe that doesn’t mean letting it flow all loose a la wild 80s rock band, unstyled and reminiscent of a she-Yeti in the woods when you’re in a board meeting – but embracing a curly style that looks polished and fresh. In short, I believe you can wear a curly style while still looking professional.”
It seems that curly hair, to some people, automatically represents a lack of seriousness. It goes against the slick-backed power suit look women are supposed to aspire to in the corporate world. Perhaps it is because curls are so unabashedly feminine.
