1. Hair Loss (Alopecia): Can be caused by genetics (androgenetic alopecia), stress, hormonal changes, or nutritional deficiencies. It includes patterns like male/female pattern baldness, alopecia areata (patchy hair loss), or telogen effluvium (temporary shedding).

2. Dandruff: Flaky scalp caused by an overgrowth of yeast, dry skin, or skin conditions like seborrheic dermatitis. It results in white or yellowish flakes on the scalp and hair.

3. Hair Thinning: Often due to aging, genetics, or hormonal imbalances. It may also result from harsh hair treatments, poor nutrition, or underlying medical conditions.

4. Split Ends: Caused by environmental damage, over-styling, or lack of moisture. Hair appears dry and frayed at the tips.

5. Dry and Brittle Hair: Often due to overuse of heat styling, harsh shampoos, chemical treatments, or exposure to sun and pollutants.

6. Oily Scalp: Overproduction of sebum by the scalp's sebaceous glands, making hair greasy and prone to dandruff or scalp irritation.

7. Scalp Infections: Fungal infections like ringworm (tinea capitis), bacterial infections, or lice infestations can lead to itching, hair loss, or scalp inflammation.

Each issue often requires tailored treatment, ranging from medical management, prp treatment to lifestyle adjustments.
