Dandruff, Hair fall and hair thinning.

This condition is called Telogen Effluvium. It's a reversible condition in which hair falls out after a stressful experience. The stress pushes large numbers of hair follicles into a resting phase. Within a few months, those hairs can fall out. Types of stress can include any hormonal issues like PCOS or any major illness like Covid. Once u start appropriate medications it takes approximately 3-5 months to start seeing any visible difference. U will know if the medication is working if ur hair loss reduces. Growth of hair will occur only post the cessation of hair loss. Dandruff will also aggravate the problem as it leads to inflammation of the scalp leading to the hair follicles getting more weaker. It's a reversible condition but needs to b treated to prevent further hair loss. Consult a Dermatologist
