SAFETY WARNING!!!
You are warned that hydrogen peroxide is very nasty stuff and can cause severe chemical burns to skin and can also cause blindness if splashed into the eyes, if handled incorrectly. Usually, you can’t buy stronger than 12% over the counter, as this is the maximum strength sold to the public and is used to bleach hair. If you want to try this, I would strongly suggest that you wear goggles and gloves to protect yourself.

The original magical “Retr0bright” gel mixture that was found to work is:-

1 pint (500ml) Hydrogen Peroxide, 10 to 15% strength (40 vol) (available from hairdressers’ supplies, e.g. the ‘Sally Beauty’ franchise in the UK)
2 heaped tablespoonfuls of Xanthan Gum (available from health food shops or online)
1 level teaspoonful of Glycerine (available from pharmacies)
1/4 teaspoonful of “Oxy” laundry booster

Add the Hydrogen Peroxide and Xanthan Gum to the blender or liquidiser. Mix on high speed for 5 seconds. Add the Glycerine and mix for a further 5 seconds. Let the mixture rest for a minute then mix again for 5 seconds. A smooth, non-drip gel should have formed. This gel can be put into a dark coloured jar or tub (e.g. a coffee jar covered in tape) and stored, as long as you DON’T add the “Oxy” until you are ready to use it.
