How to Draw Long, Straight Hair
Step 1
Start by adding some volume around the head..
Hair shouldn't lie flat on the scalp..!
Step 2
Draw the parting in your chosen place..
Step 3
Draw the outline of the hair around the face..
Step 4
Draw the direction of the hair gently flowing down over the shoulders..
Keep in mind that you're not drawing the single hairs here, just their flow..
Step 5
As I've mentioned before, hair doesn't lie flat on the scalp. Show it by elevating the front..
Step 6
Hair is grouped in strands, and that's what we see. Create skewed edges of such strands..
Step 7
Each strand can be divided into smaller strands..
Step 8
The strands we'll be partially visible on top of the head as well..
Step 9
Draw some strands on the side, too, to add some texture..
Don't draw them as simple straight lines, but rather as narrow "Y" shapes (normal and upside down)..
Step 10
Make the hair elevated along the parting..
Step 11
Outline the whole hair, following the rhythm of strands..
Don't press too hard—hair is soft and shouldn't have a hard outline..
Step 12
Draw long lines along the strands..
This will give the hair some detail and add depth to the whole haircut..
Don't press too hard, and don't make the lines too tight..
Step 13
Shade the hair now .. thinking in terms of strands .. not single hairs.
Step 14
Add some stray hairs here and there to make it look more realistic..
