- - why is my hair growing in straight (i have wavy hair) ???? - -

I put my Semen in my Wife's hair, and it straighten's out nice!

I should check out how much fluoride is in our tap water.

How old are you? My hair has done the opposite; it used to be straight, but in my late 20's it started growing in wavy. Even now, it's stick straight underneath and wavier on the top. also... is it longer than usual? the length can weigh it down and make it straight.

I'm pretty sure your hair changes over time as you get older. I hope to God mine does because I'm tired of messing with my curly hair.

My hair straightened quite a bit a few years ago. I did a lot of research which led me to the understanding that hair texture can change quite significantly throughout the lifespan due to a number of factors such as diet, chemicals, hormones, stress, etc.

I always hated my hair and my mother reassured me that my hair would probably lose a lot of its curl after about age 30 as she had experienced. I never believed her - sounded too good to be true - but it happened.

It's strange because you have to learn to deal with your hair all over again. If you're missing body, you might enjoy roller setting your hair once in a while. It's better for the hair than blow drying.

In any event, stop using products with sodium laurel/laureth sulfate or similar chemicals and if you need shine, try jojoba oil.

Oh, and here's something else... changes in your hair take time... your hair may be responding to stress, diet, or hormone changes that took place months ago.

Anecdotal stories that hormones can do this (via birth control in this example):

Xanax changing DNA:

Depakote changes DNA, too. I think this is related to people's hair changing from straight to curly and vice versa. Don't have a link on that at the moment.

Maybe your DNA has changed?

I'm sure if it's from drugs in the water or some other toxin, that there could be a way to combat it or at least fight further changes via nutrition.

I know that with some drugs you can take supplements to counteract side effects, so if you can pinpoint the nutrients related to hair texture maybe that could help you find a way to lessen the changes.

This is a fascinating problem.

I found more information on it, albeit non-official, preliminary stuff you can follow up on.

It's mostly seeming like an endocrine problem. Aren't there endocrine disruptors in the water, possibly? That term comes to mind.

I would consider getting checked out, as it could indicate a deeper problem, though not necessarily.

There are several possibilities.

One I found is the number of disulfide bonds in the hair; maybe something is interfering with this:
"The number of disulfide bonds in the hair: Simply put, the way protein structures are arranged in each hair shaft effect how hair behaves. The more disulfide bonds that occur between hair proteins, the curlier the hair and vice versa. This explains why you can temporarily alter the texture of your hair with heat and/or water — just by breaking bonds."

It could also be hormone issues, thyroid issues, medication (in the water?) side effects, or nutritional issues (B-vitamins, magnesium, zinc, biotin, and vitamin A being factors - causing or remedying, who knows?).

And the most convincing evidence, though not scientific so far, that I found was that it could be related to testosterone. If your estrogen levels are decreasing, or some other non-testosterone change happening, then the testosterone could be getting expressed more even if it hasn't itself increased.

"Excessive testosterone and /or testosterone sensitiviy can cause straight hair to go curly and/or frizzy.

In fact hair texture change such as this is often the first symtom noticed by women who develop thyroid disorders, polycystic ovarian syndrome, female androgenic alopecia, and other problems which influence and are influenced by excessive testosterone, testosterone sensitivity, a marked drop in estrogen or a combination of these things.(Women who develop thyroid disorders often become overly sensitive to normal testoserone levels, and develp androgenic symptoms)."

The same post there mentions "hormone sensitive hair follicles (high number of follicular 5-A Reductase enzyme receptors)" affecting hair texture.

Apparently the androgens getting out of control could be related to polycystic ovarian syndrome too.

So, if it was me, I'd make sure my hormones and such were ok since it could be related to a larger problem.

One more tidbit from the allnurses site:
"With little scientific evidence available about how hormones and genetics cause these texture changes, Jonathan Torch, creator of Curly Hair Solutions and founder of Toronto’s Curly Hair Institute, has come up with his own theory.
He believes changes in the muscles at the base of every follicle are the key to the changes in hair texture that take place over time. These muscular changes, he says, often come during puberty, chemotherapy or menopause, when hormones and medications may affect the muscle tone.
Sometimes these changes can be extreme, says Torch, who has witnessed many a client go from curly to straight and straight to curly.”I can’t prove anything medically,” he says. “But I have a philosophy that genetically, the muscles are changing. And this changes the shape of the follicle"

This makes sense to me, too, as our scalp can change over time just like our face and body can, and I am sure outside substances can affect that as well.

nothing worse than straight hair doom..

Are you sure that it is not HAARP?

OP are you Rh-Negative?

As one ages things like hair folicles change, along with OTHER simple things like drier skin or less need to shave the legs because there are fewer hair folicles. (Even for women!) It's no big deal, and nothing is wrong with you.

My mother's hair changed from wavy to straight but, her hair changed around menopause. I'm not near menopause, so that rules that idea out. I'm just trying to think what changes occurred the past six months that may be causing the change. I'm kind of worried the hair change may the symptom of a more serious medical problem.

your hair is getting a boner and straightening out - so stop thinking about sex you frigging perv

I've been HIV positive for 25 years. Many of the people I loved that died had hair that strangely changed. Not only whites, but blacks and hispanics. Hair does not normally straighten on African Americans. AIDS will make that happen.

I don't know if anybody has said this, but the wife who has been in the hair biz for over 22 years says you have clogged hair follicles. Hope that helps.

Jonathan is a little behind the curve. It's been well-known for many years that hair straightness has to do with the shape of the follicle and the resulting hair shaft. Straight hair has a round shaft, curly is elliptical.

Hair texture will change with age. Are you a senior?

Hormonal changes can do this. I was just talking about it with my stylist. My hair was stick straight and around puberty it started getting wavy. I'm in my early 30's now and it just keeps getting curlier and curlier as I get older.

Yes it was common knowledge about the follicles, but he's emphasizing the scalp *muscle* changes. Apparently people don't realize that the muscles change, causing the follicles to then change.

The exact thing happened to me when i was 13, stayed straight ever since but if i go to bed with wet hair in plaits, my hair goes very very wavy when i take them out.

This doesn't totally answer the why question, but does help in explaining what occurs in the lifetime of hair follicles.

Short answer is that it is a hormone-related issue. It has to be, because hormones are basically the messengers to tell our body what to do. Several things can change our hormones, including just natural aging. I suspect for you it may be something else though, as the time-frame is so short.

One thing to note is that certain plastics contain molecules that our bodies think are particular hormones (estrogen-like compounds). This usually just changes the thickness of our hair, but may be related. Check for any changes in chemicals you use and new plastic containers you drink out of. Hope this helps a little.
