Hair is held together by different types of bonds, which define its strength, shape, and flexibility. Chemical processing, bleaching, heat styling, and rough brushing can damage these bonds. Bond repair products, also called bond builders, work to rebuild or reinforce these bonds. Not all of them work the same way: some use ingredients designed to reconnect broken bonds directly, while others use acids, like citric or lactic acid, to lower the hair's pH and smooth the cuticle, reducing friction and breakage. They're generally aimed at dry, damaged, or chemically processed hair.

Progressive hair loss, also called chronic hair loss, has genetic and hormonal causes. It happens slowly, with hair getting gradually finer and less dense over the years, usually in specific areas.

Reactive hair loss can happen in response to a specific event, such as stress, illness, childbirth, a nutritional deficiency, certain medications, or a change of season. It tends to come on suddenly and all over the head, but hair usually grows back once the cause has passed.

When in doubt, consult your healthcare professional.
