What messy substance is easy to get out of your hair and wont make you rash? I'm new to this and any tips to help a long haired brunette is welcome meow

If anything has flour in it add cooking oil so it doesn't clump or it will get stuck in hair. My gf likes cake icing and mash mellow sauce since it washes out w warm water and shampoo. (She doesn't like having it put in the first place but is happy is washed out)

body lotion is a fun time, easy to clean up, and very good coverage

Cake mix in a box. Don't add anything - but warm water. Mix till very smooth. Of course try it out on a small area first.

Pudding! Especially the kind in the big cans...

Thanks everyone for the advice

Now I don't have long hair but , cake batter is fine washes out with just warm water, so does pudding, as both are water soluble which means they dissolve with enough water, shaving foam is the same way dissolves in water. whipped cream does too so does chocolate syrup. The things to avoid are Flour or more importantly gluten as it forms a paste then you get it wet , so flour or anything flour based with become a super sticky mess. Oat meal is fine washes out and its good for your skin BTW. I can relate as my skin is sensitive so certain substances give me a rash , like ketchup , mustard, peanut butter, but that just me , always a good idea to test a small amount first . Things like icing or frosting also wash out ok but take a little more effort.

Pancake syrup comes out with just hot water, don't even need soap/shampoo (though it helps get rid of the intense sweet smell.) There are several great substances that are actually good for hair and fun to play in: yogurt, eggs and honey. Other things good for hair but harder to clean up: mayo, olive oil and coconut oil.

Chocolate and strawberry syrups are wonderful for this purpose, as is whipped cream. I've had a grand experience pouring cake and brownie batters over my friends as well, and the same is true for fruit pie fillings. Puddings, caramel sauces, and egg nog have also been lovely. The trick to it seems to be to use things that are thickened with sugars, as the sucrose chains break down with exposure to water. I've been know to take someone from head to toe gunge to completely clean in less than five minutes by limiting myself to the above ingredients....
