After washing your hair with a creamy moisturizing shampoo and conditioner, you'll need to prep it for your press. Start by rubbing a heat protectant product through your mane to limit the amount of damage caused by heat.
Get those tangles out by dividing your hair into four sections --- two at top, two at the bottom. Comb out each section thoroughly using your wide-tooth comb to really get through those tangles. Once you've detangled the section, just braid or twist it to keep it out of the way.
Blow-dry each section on high heat until all of the moisture is out and your hair is straight. Concentrate on the roots, since moist roots can ruin your silky press. A good blow-dry leads to a good press, so don't rush through this portion.
Take the long end of your rat-tail comb and part a very thin section of hair going across your head starting from the nape of your neck. The thinner the section, the silkier your press will be. Clip the rest of your hair out of the way.
Turn your flat iron up to high heat and run it through the section starting as close to your scalp as possible. Move the iron to the end of your hair slowly. The slower you move it, the less likely you'll have to go back over it.
Repeat steps four through five until you've finished all of your hair. Rub two drops of shine serum into your palms and run your hands through your hair to really give your hair that California shine you're going for.
