Some mistakes that I have seen new girls make:
They try to make a lifetime supply of the sugar gel and they dont know when to stop the gentle slow boiling.
The girl might start a hard boiling and then she is left with a thick black caramel that will burn her or be so hard it's like OUCH!
Or she might have to much hair and when she applies the sugar to her hair she has practiced rolling a tiny bit in her fingertips which is good and you must practice gently rolling it... BUT if you have to many hairs you make a hair ball and you fail to gently pull the hair bulbs out of your skin. The hair bulbs come out of your skin with a gently boop that doesnt hurt and feels really clean to me.
You really must practice making the sugar so that it is light but not so light the it just sticks and doesn't pull the hair bulb out. You must practice on your legs and armpits while you are still belted.
Just a fingertip that you keep rolling on your fingertips to keep warm is perfect and as the tiny hair bulbs are added to it the sugar will remove hair bulbs more easily. It will take practice to get right.
Also another reason to practice is that you need to know how to position your skin. To get between the vagina and anus you need to be squatting and reach around the bottom. Other wise you will have a sticky mess and will not boop the hair bulbs out correctly.
If you have a bush which is not clean but women used to wear their hair like that ??? But if you have long bushy hair you must trim gently with scissors. Otherwise you will fail to get the hair bulb because you will just get tangled. Do NOT shave or you will get ingrown hair infections but gently snip until it is as long as your leg hairs were when you practiced sugaring your legs.
I hope that helps and if you make mistakes your first time please just adjust and fix it do not feel bad or be to hard on yourself and get some help so that you do not burn or tear your skin. Think before you do anything just like spraying ice water or hot water under your belt.
