Henna: color your hair without damaging it

I've been reading Henna Blog Spot and I found a few very interesting pieces of information, I want to copy-paste it here to remember. I've seen some of these questions answered before, but a few of them are questions for which I've never found answers. All and all the 3 entries are very informative and if you're curios about henna you should check them out.

I wrote about henna before in my Minimize chemical dye damage and alternatives entry, there are a few very good articles about it linked there as well.

"1. The sand test: Place a pinch of henna between 2 glass surfaces. If you hear a scratching sound and/or the glass has been scratched, there is added sand in your henna powder. Adding sand is a technique used by some vendors to stretch their henna powder to make more profit. We do not do that here at Henna Sooq as we want our customers to have the very best.

 2. If your henna powder looks abnormally bright green, and a green dye pools after you’ve mixed the powder with water, there is green dye added to the powder. Avoid this powder as it will alter the hair colour results,especially if you have lighter coloured hair.

 3. Mix up a teaspoon of henna, with warm water and dye some loose shed hairs with it. When the hair has been dyed, mix 1 ounce of 20 vol peroxide with 20 drops of ammonia. Add the hair strands to this solution. If nothing happens, you have pure henna. If the hair strands turn green, melt, boil, change colour immediately, or smells strange (not like grass), then that henna has been tainted with metallic salts. Do NOT use this henna on your hair."

"Henna also imparts a temporary resin, which can easily be removed with a clarifying baking soda rinse (which is followed by a diluted vinegar rinse of 2tsp vinegar to 2.5 cups of water and a deep moisturising treatment)"

"To keep henna and herbs  (excepting Indigo powder which should live in the refrigerator) fresh, they should be sealed and stored in the freezer.  Henna powder will not lose it’s potency if it is stored in the freezer.  Some people have reported  still achieving exceptional stains with henna that has been stored in the freezer for a number of years."
