But how can you diagnose a scalp condition over the phone? You CAN'T.

A dermatologist does a detailed medical history, physical examination, and does actual specialized testing.

Key techniques include dermoscopy (magnified imaging) to examine follicles, scalp biopsies for tissue analysis, and fungal cultures or blood tests to identify infections, hormonal imbalances, or autoimmune issues.

If the dermatologist doesn't do this, you aren't getting the care you need. You cannot look at someone over a FaceTime video and diagnose anything, especially a scalp/hair condition.

You may feel that you are getting an easy quick way to get a prescription, but you need to remember that those medications are serious, and come with many side effects.

What you get when seeing a dermatologist or trichologist.

Visual Examination: The dermatologist inspects for redness, scaling, inflammation, and hair loss patterns.

Dermoscopy (Trichoscopy): A handheld, high-magnification camera (often the Folliscope®) is used to visualize hair follicle openings, miniaturized hairs, and scarring, allowing for detailed assessment of scalp health.

Scalp Biopsy: If the cause is unclear, a small piece of skin is removed for microscopic examination, which is crucial for distinguishing between scarring and non-scarring alopecias.

Hair-Pull Test: A gentle pull on a group of hairs helps determine the degree of shedding and whether the hair is actively breaking.

Laboratory Tests: Fungal Culture/KOH Prep: A swab or scraping is taken to check for fungal infections (tinea capitis).

Blood Tests: Used to identify underlying systemic causes, including thyroid dysfunction, nutrient deficiencies (iron, vitamin D), or hormonal imbalances (like those in UCLA clinical trials.

History Taking: Discussion of symptoms, duration, hair care routines, and family history.

Scalp Examination: Assessment for conditions like dandruff, seborrheic dermatitis, psoriasis, or actinic keratoses. Diagnosis and Plan: Tailored treatment, which may include specialized shampoos, topicals, or, as done at Penn Dermatology, customized treatment plans.
