Please help me raise money for Dogs Of The Streets - the more money I raise, the more hair I'll cut!*(see below)

My hair has always been my pride and joy and I've always said "I won't cut it until at least after I've got married"...
Seeing as I've spotted my first grey hair I'd rather have someone else be able to enjoy my hair before I turn completely grey!
The charity that I will be donating my hair to is the "little princess trust" http://www.littleprincesses.org.uk/about-us/
They require a minimum of 7 inches (~18cm) which will give a young cancer or alopecia patient a short-haired wig.
Hair with the length of at least 12 inches (~30cm) will make a lovely long haired wig for a girl.

Another charity that I would love to support is a very new charity that helps with the care and health of pets of people who live on the streets of London.
The charity is called DOTS - Dogs on the Streets London. http://dotslondon.co.uk
They have started setting up weekly stations where homeless people can go for preventative and basic veterinary care for their dogs, and if needed they get referred to the Blue Cross for surgery.
They also provide basic items like collars, leads and bowls but more importantly appropriate dog food!
A lot of street dogs are surprisingly overweight due to a very unhealthy diet of junk food.
With the help of donations, DOTS provides homeless people with healthy food for their dogs, even some treats aimed to keep their teeth in good shape, and basic veterinary care by the street vets.

The big day is planned for the 1st of July!!

*The total amount of money raised by the 1st of July will decide the length of hair I'll be donating as follows:
£300 = 7" (17.8cm)
£400 = 8" (20.3cm)
£500 = 9" (22.8cm)
£600 = 10" (25.4cm)
£700 = 11" (27.9cm)
£800 = 12" (30.5cm)
£900 = 13" (33cm)
£1000 = 14" (35.5cm)
