Frequently Asked Questions
When hardened, the gel forms microscopic pores that allow water and oxygen to pass through. This can be seen under a microscope, and we demonstrate it in-salon with UV curing and water drop tests.
Yes — the Egyptian Dar Al-Ifta has issued a fatwa permitting it. Water and oxygen pass through the gel's microscopic pores, and we have scholars who regularly use our products.
"Porous gel" is a description, not a brand name. The product is branded under Havana, which shares the same keratin-based composition as natural nails. Havana is the exclusive distributor.
A nail extension is a plastic piece applied to short or broken nails at the tip only. It does not prevent wudu because it is attached only to the tip of the nail, not the skin.
All treatment layers — including the base, color, and top coat — are porous, allowing approximately 12.5% water and oxygen permeability. Each layer is tested and verified in-salon.
Porous gel lasts 14–20 days. A refill is recommended after 14 days because the material begins absorbing water more deeply over time, which can affect nail health if left too long.
Using a safe, professional remover that does not damage the natural nail. We never use harsh soaking methods that compromise nail integrity.
No, it is safe. For extra caution, sunscreen or UV-protective gloves can be used during curing.
No — as long as refills are done on time and nails are checked between sessions. We inspect nail health at every appointment.
Yes, but it is recommended to remove it within 1–2 days and briefly soak the nails to eliminate any chemical residue that could block the pores.
Heat activates the amino acids and silk proteins in the formula, helping them penetrate and seal the hair cuticle. This is what delivers the smoothing and protective effect.
No — it smooths rather than fully straightens. Expect approximately 20% curl reduction and significantly less frizz. Up to ~80% smoothing is possible since the formula is formaldehyde-free and results can be customized.
Yes. The results can be customized depending on your hair goals — from deep hydration with minimal smoothing, to maximum frizz control.
No. Other root treatments on the market contain formaldehyde, which can damage hair. Chi Enviro is applied to the full length to ensure consistent, safe results.
It is recommended annually as a protective treatment. The effects build with each session, and regular use helps maintain long-term hair health.
The treatment removes accumulated chemicals and minerals from the hair shaft. This deep-cleansing effect can cause slight lightening in color-treated hair — it is a sign the treatment is working.
The solution is composed of 100% safe amino acids. There are no harsh chemicals, bleaches, or acids involved.
Using a nano-needle device (Must Pro) applied at a 2mm depth. The solution is introduced through the skin's pores to lift and expel the pigment — without injections, cutting, or burning.
Typically 2–3 sessions. The exact number depends on the depth and density of the original pigment.
21–30 days between sessions. This allows the skin to heal fully and the ink to continue exiting naturally before the next treatment.
No. The procedure is completely safe and non-destructive. There is no burning, no scarring, and no damage to surrounding skin.
Ink begins exiting during the session and continues lifting over the following 30 days. Full results are assessed after the healing period.
Yes. The technique is applied at a superficial 2mm depth without injections, bleeding, or permanent scarring. It is temporary, fades naturally, and is widely considered permissible.
No — there is no pain, no blood, and no scarring. The nano-needle works at a very superficial level, making the experience comfortable for most clients.
No. The pigments used are natural herbal-based ("Nano Blading Ink") and do not oxidize with blood or shift in tone. The color fades gradually and evenly.
Approximately 1–1.5 years. The result fades naturally over time — no removal procedure is required.
We use a natural herbal pigment specifically formulated for superficial semi-permanent brow work. It is skin-safe and does not contain heavy metals or synthetic dyes.
The treatment uses plant-derived (clay-based) stem cells imported from L.C., USA. These mimic the behavior of human stem cells and stimulate collagen production without any animal-derived ingredients.
No — trained specialists perform it. The treatment is non-invasive and does not require medical supervision, making it accessible as a regular skincare service.
2–3 sessions are recommended for visible and long-lasting results. The treatment addresses fine lines, pigmentation, uneven skin tone, and acne over the course of sessions.
The Stem Cell Facial stimulates collagen, improves skin tone, reduces wrinkles, pigmentation, acne, and dark circles. Results improve progressively across sessions.
We use L'Oréal, Indola, and Schwarzkopf — all professional-grade brands chosen for their quality, consistency, and range of tones.
A coloring process performed with a protective protocol using products from CHI and L'Oréal. The goal is to deliver color while actively maintaining hair health — reducing damage and chemical stress during the process.
A specialized adhesive with micro-pores that allows water and oxygen to pass through. It is lighter than traditional lash glue, reducing weight on the natural lash and allowing breathability.
Yes. The porous adhesive is water-resistant. After swimming, gently brush the lashes with a clean spoolie to maintain their shape and alignment.
Yes. The porous glue does not block water from reaching the skin or lash line. Ivy Lash extensions are permissible for prayer.
Havana's pricing reflects three things: imported, professional-grade materials; specialists trained to a high and consistent standard; and guaranteed quality with after-service care. Beauty treatments are an investment in yourself — Havana ensures that investment is safe, lasting, and worthwhile.
