Start with the hair problem
Is your hair dry to the touch, breaking from chemical processing, frizzy in humidity or simply difficult to style? These concerns are related but not identical. A conditioning session may improve softness, while a smoothing or straightening process aims to change how hair looks and behaves for longer. A consultation should establish what you actually want.
What Sai Meher lists
Sai Meher’s hair-treatment menu includes Hair Protein Treatment, Natural Hair Treatment and Keratin Treatment. The Natural Hair Treatment specifically lists a hair mask, wash, steam, vitamin serum and head massage. The website describes different prices for these options; final pricing for keratin depends on hair length and condition.
Be careful with the word “keratin”
Some products sold as keratin or smoothing treatments involve chemical processing and heat. Product chemistry differs substantially, and some smoothing formulas can release irritating fumes when heated. Ask to see the exact brand and ingredient or safety information and discuss ventilation, sensitivity and pregnancy-related concerns with an appropriate clinician if relevant. Do not assume “keratin” always means a gentle hair mask.
Protein is not always the answer
Hair can feel stiff or coated when too much product is layered on without matching its needs. A protein-labelled treatment does not guarantee repaired hair structure or stronger growth from the follicle. Likewise, “natural” on a service menu should be understood as the name of a treatment, not proof that every ingredient is chemical-free or hypoallergenic.
Aftercare and Bangkok weather
Ask whether your treatment changes how soon you can wash, swim or tie up your hair, and which shampoos are recommended. Humidity may still affect the finished look, especially as a smoothing result gradually wears off. If you frequently colour, bleach or heat-style, give your beautician that history before adding another service.
Frequently asked questions
Is keratin the same as permanent straightening?
Not necessarily. Exact results and chemical processes vary by product and technique.
Which treatment suits damaged hair?
That depends on the cause and extent of damage; ask for a realistic assessment before choosing.
