What type of hair loss do I have? (photo)

Thank you for your question, This needs an in-person evaluation. I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

From the pictures you have sent, it seems like you may be experiencing Chronic Telogen Effluvium. Although some women with Female Pattern Hair Loss (FPHL) exhibit bitemporal recessions, Chronic Telogen Effluvium (CTE) patients have bitemporal thinning without associated thinning of the “top-scalp”. Close inspection of FPHL reveals miniaturized hairs of varying short lengths and decreased caliber, while in CTE there is a general absence of miniaturized hairs.
Excessive, alarming diffuse shedding coming from a normal looking head with plenty of hairs and without an obvious cause is the hallmark of CTE, which is a distinct entity different from Female Pattern Hair Loss.
The exact pathogenesis of CTE is not known, but it is theorized that it is due to reduction in the duration of anagen growth phase without miniaturization of hair follicles. Also, the etiology of CTE is unclear and it is diagnosed after excluding other causes of chronic diffuse hair loss. Obvious diffuse thinning is not a feature of CTE, though many of these women do notice 50% reduction in the volume of their ponytail thickness. Moderate to severe bitemporal recession may also be seen.
Apart from complete blood count and routine urine examination, levels of serum ferritin and T3, T4, and TSH should be checked in all cases of diffuse hair loss without a discernible cause, as iron deficiency and thyroid hormone disorders are the two common conditions often associated with diffuse hair loss, and most of the time, there are no apparent clinical features to suggest them. CTE is often confused with FPHL and can be reliably differentiated from it through biopsy which shows a normal histology in CTE and miniaturization with significant reduction of terminal to vellus hair ratio (T:V < 4:1) in FPHL.

In  my opinion you need to visit a hair loss expert for an in person consultation. They will do a history, examination with magnification and woods lamp, blood work and possibly biopsy. The main  differential diagnosis includes telogen effluvium, androgenic alopecia and scarring alopecia. Good luck.
