Heat + Hair growth

[frangipani]

Browsing the vogue website, i came across this tidbit:

"Good news if you’re trying to lengthen your locks this season: hair grows faster when the mercury hits high. “Hair and nails grow faster in summer due to humidity as heat stimulates growth,” waxing expert Gilly Harriott tells us. Not so good for the hair on your legs."

Is there any truth to this, or is it a load of baloney ? It sounds a bit suspect ...

From what I know hair really does grow faster in the summer... Something to do with the heat and the increased blood circulation I think..?

Yes, generally hair does grow slightly faster in Summer for most people. Probably a mix of increased levels of vitamin D, humidity, sunshine and warmth. However blasting your hair with a hair dryer/living in a greenhouse/using sunbeds to try and mimic the same effect won't help.
Winter is generally resting time for hair so it won't grow as fast, your body is concentrating on reserving energy in colder months so it won't be expended on hair growth etc from what I understand.

It's true, hair does grow faster in warmer climates, a fact that's been known for years! Google information, there's loads of it to be found.

I live in New England, graduating high school with a girl who moved to Florida for a year.

Her hair was around mid-back length when she moved there but when I saw her, two years after graduation, her hair was literally to the floor.

Now, keep in mind she is around 5 feet tall and genetics most likely played a part but that much growth in that short span of time was mind-blowing!

When questioned about it, she stated it grew like a weed while she lived in Florida!

The killer was it was not damaged in any way and was extremely thick, with a blunt hemline.

hm, actually, i noticed more growth in winter than in summer guess that depends more on hormones rather than season (or heat)

Hooray, more reason to chase summertime around the world
Weird, i would have thought hair would grow faster in a cold climate, since its function is to keep you warm. The mysteries of the human body!

I also notice more growth in summer, but nothing like 1'' more... just a bit. I believe it's due to the warmth and higher vitamin D levels. I doubt humidity has something to do with it. Here in Germany humidity is also high in winter, but the hair doesn't grow faster. I'd relate faster growing simply to more sunlight.

A lot of people I know and articles I've read have stated that hair grows faster in warmer climates, most likely due to people being more active in the summer, more exercise, more blood flow, the temperature itself, etc. More vitamin D from the sun as well.
There are a lot of factors that could easily confirm the claims.
I never noticed much of a difference personally, but then again only recently have I started keeping track of my monthly/yearly/seasonal growth.

It is said that hair growth speeds up in summer months, for me though winter is my growth spell. However the avarage growth is 6" a year, whenever you get this is normal for you.

Though i hope the sun helps my hair as I am off to the far east tomorrow for a fortnight so who knows!

The one year that I kept measurements all year, my hair grew fastest from July -- January, then slowed down from January -- June. July through September are the hottest months around here, but October through January definitely are not.
