Hair can change with age. A once-straight texture may become wavier, strands may feel finer or drier, and the scalp may become oilier or more sensitive. Hormones, genetics, follicle shape, chemical processing, nutrition, health conditions, and daily habits can all contribute.

Why Hair Texture Changes
- Hormones and ageing: changes in estrogen, androgens, or thyroid function can affect the hair cycle and strand quality.
- Genetics and follicle shape: the shape of the follicle influences whether hair grows straight, wavy, or curly.
- Scalp condition: oil, irritation, dandruff, and buildup can change how the roots and hair feel.
- Chemical and heat damage: coloring, perming, straightening, and hot tools can alter the cuticle and reveal uneven texture.
- Nutrition and health: low protein or micronutrient intake and some health conditions may contribute to fragility or shedding.
- Stress and environment: stress can affect the hair cycle in some people, while humidity, pollution, and water quality affect manageability.
Sudden or patchy hair loss, scalp pain, sores, marked itching, or rapid texture change should be assessed by a dermatologist. A Head Spa supports cleansing, comfort, and a consistent care routine, but it does not diagnose the cause of hair loss.

How Siesta Programs Support the Scalp and Hair
- Signature Scalp Program: cleansing, exfoliation, and Thai-inspired therapist-led massage.
- Aroma Oil Tranquility Program: an aromatic care flow designed for scalp comfort and relaxation.
- Water Flow: an add-on using comfortable water flow and hydrosols to extend the cleansing and sensory experience.
Massage may temporarily stimulate circulation in the area being worked on and support the overall scalp-care experience. It does not guarantee regrowth or prevent shedding from every cause.
How Often Should You Book a Head Spa?
For general scalp care, every 2 to 4 weeks is a practical rhythm. The most suitable frequency depends on scalp condition, daily habits, and the selected program. A therapist can recommend an interval based on the condition observed during the visit.
