Conditions We Investigate
Recognize the pattern. Then let us investigate it.
These overviews are intentionally brief — enough to help you recognize what you are seeing and decide whether an evaluation makes sense.
Androgenetic Hair Thinning
A gradual, patterned change in hair density that often follows family tendencies and can appear differently in women and men.
Read overviewExcessive Shedding (Telogen Effluvium)
A period of noticeably increased shedding that commonly follows a physical or emotional stressor several weeks or months earlier.
Read overviewTraction-Related Hair Loss
Changes associated with prolonged tension on the hair, often along the hairline, temples or nape.
Read overviewPatchy Hair Loss (Alopecia Areata)
Distinct, often round areas of hair loss that may appear suddenly and can change over time.
Read overviewCentral Centrifugal Scarring Hair Loss (CCCA)
A progressive change that typically begins at the crown and spreads outward, more commonly observed in women of African descent.
Read overviewScalp Inflammation & Flaking
Ongoing irritation, flaking or redness that can accompany — and sometimes contribute to — hair changes.
Read overviewPostpartum Shedding
A common period of increased shedding in the months following childbirth as hair cycles resynchronize.
Read overviewThyroid & Nutrient-Related Changes
Hair and scalp changes that may be associated with thyroid function, nutrient status or other wellness factors.
Read overviewMenopause, HRT & Hormonal Change
Hair and scalp changes that many women notice through perimenopause and menopause, as hormonal patterns shift and the hair cycle changes with them.
Read overviewGLP-1 & Rapid Weight-Loss Shedding
Increased shedding reported by some people during rapid weight loss, including while using GLP-1 medications. It is generally associated with the pace of the change and the nutrition that accompanies it rather than the hair itself.
Read overviewScalp Health as the Foundation
Hair grows from an environment. When that environment is inflamed, congested or persistently uncomfortable, the hair it produces often reflects it — which is why we evaluate the scalp before recommending anything for the hair.
Read overviewHormone Replacement Therapy (HRT) & Hair
Hair often responds when hormone therapy begins, changes dose or ends. Tracking the hair alongside the therapy — in coordination with your prescriber — is what turns a worrying season into a documented pattern.
Read overviewHealthy Aging Hair
Hair changes with time: diameter, density, pigment and scalp condition all shift. Some of that is ordinary aging, and some of it is a pattern worth investigating — telling them apart is the point.
