To minimize hair loss, be as gentle as possible with your hair during your course of treatment:
Wash your hair only once a week or less.
Use only sulfate-, silicone- and paraben-free shampoos. (If you have dyed or overprocessed hair, continue using your usual products.)
Avoid hair-styling products, such as gels and creams.
Refrain from dyeing, heat-styling and blow-drying your hair.
Limit combing to once a day.
Don't put your hair in tight ponytails or buns.
Avoid hair extensions (including sew-ins, weaves, lace front wigs, braids and crochets). They can stress your hair and worsen shedding or block scalp contact with the cold cap.
Avoid touching your hair, which can jostle the roots, and limit contact with rough materials. Use satin or other soft, tightly woven pillowcases.
