Remember that old wives tale about brushing your hair 100 strokes to get it to grow and/or shine? Well its true. But only if you haven't washed your hair in about three weeks.
In Beauty School our clientele was 80% age 70+. I don't know why exactly these old ladies believe that showering erases your soul, but the point is, they are not washing their own hair. This generation was reared to brush the natural oils throughout their locks to keep them healthy and shiny. Scientific brushing has been taught in Beauty Schools for decades to keep this natural remedy alive.
Brushing your dirty hair with a boars hair brush will exfoliate the dead skin from the scalp and distribute the natural oils down toward the dry ends where it thirsts for this smelly healing nectar. The problem is that most of us shampoo long before our scalp has enough time to produce enough oil to reach the ends anyway, so we have to find another solution. Conditioner*.

If you want the most relaxing treatment of a lifetime, find a stylist that offers scientific brushing as part of their deep conditioning treatment*. OMG. Amazing. So here's what happens, because you can make up your own mini version at home!
I would recommend making the appointment on a day that you can relax - oh and not wash you hair for several days prior! Perfect for when your man is away or after your birthday massage ;)
So this amazing, rare stylist is going to take down your dirty matted hair and slowly brush every inch of your tired oily head. We brush the dead skin and build up and oil away from the scalp and down towards the dry ends. In the salon, we add treatment oil* to the ends, and aromatherapy essential oils* to the scalp or brush. At home you are going to add some oil to your brush to get the same effect. I recommend starting with a few drops of olive oil or grape seed oil.

Then relax and enjoy a steamy shampoo massage! I always tell my guests to only shampoo* the scalp and condition* mid shaft - ends. Wrap a hot steamy towel around your shoulders so you can relax with your feet on the rim of the tub while your conditioning mask* sinks in! If your hair is super dry and crunchy, try adding a few drops of olive oil or grape seed oil to your conditioner for the ends.

Rinse with cool water (for shine and easy detangling) and towel dry. Turbans are not allowed. I know how tempting and convenient a towel turban is, but remember your hair is in a vulnerable state when wet so I will tell you the healthy way:
Squeeze the excess water out while still in the tub/shower. If you must wring, do so in the middle of your length. Use your towel to blot and squeeze the dripping hair and let it air dry as much as possible. Sure it is going to start drying inconsistently and showing frizzes in weird places. It's OK, that goes away as soon as you comb through and disperse the water.

Apply a detangler*, leave-in*, or serum* now. STARTING AT THE BOTTOM with a soft bristle brush, detangle from the bottom working up to the root.
A) 100% air dry. Apply a de-frizzer or serum* to polish the fly aways.
B) Apply light/medium hold styling agent* and blow-dry the scalp only, then wrap the hair in a loose bun to dry with big loose waves. This works well with the windows down in the car on the way to work too!
C) Apply Sea Spray* or curl enhancer* and diffuse with warm air. For a new twist, divide your hair into about 7-10 little ponytails, apply medium hold gel*, and "fidget twist" them up into little mounds and pin to secure (Think Jada Pinkett Smith in Matrix 2). Air dry or Diffuse*. Take the twists down when completely dry for shiny defined Bohemian Beach curls.
D) Apply a smoothing serum* and thermal protectant* and Flat Wrap hair straight while paddle brushing* it dry using the concentrator nozzle* on your dryer. Reapply thermal protectant and touch up bothersome flyaways with a Smoothing iron* or curling iron.
E) Spray* to set.
