Oral low-dose minoxidil has emerged as an alternative to topical formulations for hair loss treatment, with studies suggesting systemic administration may benefit patients who experience scalp irritation from topical application. Cardiovascular monitoring is indicated for oral use.

Minoxidil and its use in hair disorders: a review.

Figure 1
Figure 1

Treatment options for androgenetic alopecia range from FDA-approved pharmacological agents (minoxidil and finasteride) to emerging therapies including low-level laser therapy, platelet-rich plasma, and hair transplantation. Efficacy, side effect profiles, and patient compliance vary substantially across modalities.

Fig. 1. Clinical example of female pattern hair loss
Figure 3 Photograph

A clinical photograph demonstrating female pattern hair loss, showing characteristic diffuse thinning across the crown and mid-scalp. FPHL affects women with varying degrees of severity and may lead to significant psychological distress.

Female pattern hair loss: A clinical, pathophysiologic, and therapeutic review.

Fig. 2. Ludwig scale representation
Figure 4 Diagram

The Ludwig scale classifies female pattern hair loss into three progressive stages, ranging from minimal thinning at the crown (Grade I) to extensive hair loss across the top of the scalp (Grade III). This grading system remains one of the most widely used clinical tools for assessing FPHL severity.

Fig. 3. Sinclair Scale Sinclair’s classification. MPA is divided into four levels of intensity on the basis of normal scalp to the left (Sinclair et al., 2005).
Figure 5 Diagram

Sinclair's classification divides midline pattern alopecia into four intensity levels, progressing from a normal-appearing scalp to increasingly visible widening of the central part. The scale, introduced by Sinclair et al. (2005), provides a practical visual reference for clinicians assessing hair loss severity.

Fig. 4. Olsen´s classification. Olsen patterns incorporate the accentuation of the front-overtical alopecia, which has a triangular or Christmas tree form with hair loss in a triangular form in the front-overtical area (Olsen, 2002).
Figure 6 Diagram

Olsen's classification system highlights the characteristic triangular or Christmas-tree pattern of frontovertical alopecia seen in female pattern hair loss. The accentuation of thinning at the frontal midline distinguishes this pattern from the more diffuse Ludwig classification.

Figure 7

A summary of clinical evidence supporting combination therapy with topical minoxidil for androgenetic alopecia in both men and women. The data, compiled by Varothai and Bergfeld (2014), indicates that multi-modal treatment approaches may offer improved outcomes compared to monotherapy.

Androgenetic alopecia: An update.

Fig 3. Dihydrotestosterone (DHT) synthesis by SRD5A2 in AGA. The SRD5A2 synthesizes DHT by converting testosterone in the presence of NADPH to DHT.
Figure 3 Diagram

The DHT synthesis pathway via SRD5A2 is diagrammed, showing how 5-alpha reductase converts testosterone to dihydrotestosterone in the presence of NADPH, the key hormonal driver of AGA.

Figure 4 Diagram

Finasteride's mechanism of inhibition is depicted at the molecular level, showing covalent adduct formation between NADPH and finasteride that prevents further hydride transfer to testosterone.
