I don't have thick hair, but here's what I do....
Wash and condition with Keracare Detangling Poo & Humecto.
Towel Blot hair.
While Damp: Detangle using a combination of Salerm 21 & Potion 9 as leave ins.
Put a little oil in my hair and PM Super Skinny Serum.
Part hair in 4 sections with clamps and airdry.
Apply a
little Super Skinny to each section as I take down, (sometimes I use Frederic Fekkai glossing cream also
) for heat protection.
Since the hair was previously detangled I can then use a small tooth comb and comb through each
small section I'm about to flat iron.
1, maybe 2 swipes max. Working from back to front.
A little Mizani Shyne when finished or FF glossing cream.
Voila! Shiny, straight, bouncy hair.
1 hr start to finish (dry hair of course)
Hope this helps!
