I preheat conditioner oils before applying them?

I wash before freezing, sometimes I even cut them, because then I can use them straight out of the freezer after they've defrosted.

If it has been 24 hours, I don't think so. It's the same when someone sends you a sentence in the "chat" and you don't open it. It expires after...

Yes, you should. Don't forget the after treatment.

Basically, fragrance oils are synthetically produced, while essential oils are natural. I personally don't recommend using fragrance oils because they can cause a lot of allergies and you'll be breathing...

This is not recommended. You're going to open it to put the meat in, and get "smoked" in the face.

No. You have to hold the extensions against your hair and then apply the heat. Heating the keratin on the hair creates a bond that attaches it. You then roll...

You don't have to, but it is much healthier for your face, as it can prevent acne and clogged pores.

It makes your makeup last longer, as well as making your makeup look fresher.

You don't have to, but it is advised. Before you send the EPK, make sure you have all the contents present and updated.

You should do both. Washing your face first gets rid of the excess dirt and oil, making the mask more effective. Washing your face afterwards gets rid of any residue...
