Head cover having selectable size and location of opening for exposure of a portion of a user's hair

A protective head cover having selectable size and location of at least one opening for exposure of a portion of a user's hair to an external hair treatment environment, comprising:

• an impermeable outer surface of the protective head cover that protects hair thereunder from an external hair treatment environment;
• a main opening that receives a user's head inserted into the protective head cover;
• at least one opening on the protective head cover, separate from the main opening, the at least one opening having an opening size that is selectable from a plurality of selectable sizes for the at least one opening and having an opening location that is selectable from a plurality of selectable locations for the at least one opening on the protective head cover, thereby the at least one opening being suitable for selectively exposing through the at least one opening a portion of the user's hair from under the protective head cover to an external hair treatment environment while protecting another portion of the user's hair, that is covered under the protective head cover, from the external hair treatment environment;
• an elastic band extending along a circumference edge of the at least one opening;
• a partition of material running down a middle region of an interior shell of the protective head cover and extending inside the protective head cover laterally across the at least one opening while being spaced away from the at least one opening sufficient to allow a tuft of hair to be pulled from inside the head cover and through the at least one opening;
• and
• a flap at least partially covering the at least one opening on the protective head cover, and with a first plurality of user selectable attachments located along an edge of the flap, that mates with a corresponding second plurality of user selectable attachments along the outer surface of the protective head cover, each pair of matable first user selectable attachment from the first plurality and corresponding second user selectable attachment from the second plurality being openable with the first user selectable attachment from the first plurality and corresponding second user selectable attachment from the second plurality being unattached to each other thereby exposing a portion of the at least one opening on the protective head cover, and being closable with the first user selectable attachment from the first plurality and corresponding second user selectable attachment from the second plurality being attached to each other thereby the flap covering the portion of the at least one opening and protecting hair thereunder.
