When I was a kid Seventeen always had those back pages full of hair growth pills and such. Silly, yes. But I’d like to have longer hair by the time my wedding rolls around (I have until October - well, let’s say August or September because of pictures) - not Crystal Gayle longer, just long enough to give me more options.
Does biotin work? Is there anything else that does? (Actually, and safely?)
Getting pregnant does cause your hair to grow well…but that may not be a good strategy for a wedding.
I took biotin a while back to help strengthen my fingernails. It helped them grow out a bit faster too but I can’t confirm this 100%. I did also note a slight difference in my hair growth as well, it seemed to grow in a bit faster and was definitely thicker and stronger.
It takes a few months to see results but it’s the only supplement I know of that targets hair and nail growth.
Some have developped acne while taking biotin (I did not experience this) otherwise there are no side effects that are notable.
I take biotin supplements and can confirm that they do make nails and hair grow a bit faster and a lot stronger - which helps, because you get less breakage/split ends. However, if you reallyreallyreally want longer hair, I suspect nothing you take will work fast “enough.” 
Well, it doesn’t need to be tons longer, just long enough to curl without looking like Annette Funicello, or a little old lady, both of which invited comparison last night when I dusted off my hot rollers.
Hair extensions or an updo with a hairpiece are good options for wedding hair. I wouldn’t want to risk the acne side effects, because your face matters more than your hair in those pictures.
Some people find that taking a prenatal vitamin helps, pregnant or not. Check with your doctor first if you take anything else or have any health conditions, of course.
I swear by horsetail (Equisetum arvense) and nettles (Urtica dioica) for improving the look of nails and hair, but I don’t know that there’s any scientific proof for that, just my experience and a few thousand years of traditional use.
No. Way. For one thing, I don’t need it that long, and for another… just no.
In Durk Pearson’s long and (as Linus Pauling put it) “somewhat confusing” book Life Extension, he states that supplementation with the sulfur-containing amino cysteine (not cystine—there’s a difference) will increase hair growth, making it at least thicker. He also states that cysteine is routinely added to the feed of wool-producing sheep, because it increases total wool output by 14%.
Peanut butter. Just don’t mix it too runny. 
I’ve been through a course of hair replacement/rejuvination therapy (and yes it worked). Part of that was using a shampoo that made your hair grow more quickly, and holy mother did it work.
Whenever I’ve been out in the sun for several days in a row, my hair and nails grow like the bejezus and I have to shave more often. So vitamin D?
I suggest wearing platform soles.
In husbands?
I’ve noticed that growth of my hair and nails fluctuates. It seems dependent on my overall state of health.
During both pregnancies my hair grew especially fast and I suspect that pregnancy and the prenatal vitamin both played a part.
Some people claim that by daily scalp massage you keep a good blood flow to the scalp which encourages faster growth.
Unfortunately, it’s well documented that zombies can NOT grow hair, and actually tend to lose any they have rather quickly.
My mother-in-law, on advice from another old lady from the shtetl (Jewish hick village in The Old Country) for a while–recently, in NYC–washed her hair with onions to thicken her hair. I shit you not.
How my brilliant wife turned out the way she is still amazes me.
How quickly? Real question.
Not about zombies, but normal still-dead people.
Depends very strongly on how they’re stored.
Mummies (or stored in very arid conditions) don’t actually lose much at all. There are mummies of childrenwith creepily perfect hair, even down to the fair downy hairs on their faces and arms.
If a corpse is left out in the open, hair will either get harvested by various birds and animals, or will “fall out” when the skin decomposes to the point that the hair can get tugged or blown free of the body. That can happen within DAYS depending on conditions.
In a coffin? Somewhere between mummies and open-air corpses, depending on the humidity, the air content, and the seal on the coffin.
Check out this wikiabout how we study the processes now: NOTE - NOT FOR THE SQUEAMISH OR FAINT OF HEART.
Computer froze and I couldn’t edit again: the wiki linked is to a general overview of the locations of the research facilities - the links and resources at the bottom have the actual articles on studies of decomposition.
