Understanding Your Straight Hair Type (Type 1)Updated 3 days ago

Type 1 Hair: Straight Hair

Type 1a hair is 100% straight. There is no hint of curl pattern or wave, it’s simply straight and flat as a pin. Another defining feature of type 1 hair is its thinness. The benefit of this particular texture is that it tends to effortlessly maintain its shine.

Structure: Round follicle, uniform keratin alignment, low resistance to oil movement

Biology: A round follicle creates a uniform fiber with even tension distribution
Cuticle lies flat and compact.

Hair Behavior:

• Gets oily quickly at the roots
  
  

• Can look flat or lack volume
  
  

• Product buildup shows faster because nothing blocks the distribution to the ends
  
  

• Needs lightweight formulas that don’t weigh hair down
