Henna can mean two different beauty services
Decorative mehndi on skin and henna for hair share cultural roots, but they are not the same appointment. A skin design is meant to stain temporarily; hair henna is used to colour strands. At Sai Meher, Henna / Mehndi for Hair appears in Hair Styling, while hand and bridal mehndi are listed on a separate service page.
Why the formula matters more than the label
Pure henna, plant blends and products marketed as “henna hair colour” may contain very different ingredients. Some mixes include indigo or additional colourants. Never assume that a dark or quick-working product is pure henna; ask for an ingredient list and suitability assessment. If you have ever experienced a rash after hair dye or temporary black henna, mention it before treatment.
What to expect from the colour
Traditional henna generally deposits warm reddish tones, although results vary with starting colour and the formula used. Some people like the dimensional result; others want a colour change that is difficult to achieve with henna alone. Chemical hair colour may offer a wider range of shades but carries its own sensitivity and hair-damage considerations.
Think ahead to your next colour appointment
Previous plant dyes can affect how later chemical colouring or lightening proceeds, particularly when the composition is unknown. Tell the stylist everything you have used, including box dyes, bleach, colour shampoos and henna. If you want highlights in a few months, bring that up before choosing today’s treatment.
Bangkok aftercare
Condition lengths according to how they feel, protect hair from excessive heat and avoid rough towel drying. As with any colour, prolonged sun and repeated washing can influence the appearance over time. If your scalp burns or itches during application, stop and alert the professional rather than waiting for the colour to process.
Frequently asked questions
Does henna lighten dark hair?
Pure henna deposits colour; it does not act like bleach to lighten naturally dark hair.
Can I highlight hair after using henna?
Possibly, but the stylist must know the exact previous product and may need to assess compatibility first.
