To pick a hair salon in Mariano Roque Alonso, decide first what you need (cut, beard trim, colour or straightening), then look for a place on your daily route: along Ruta PY03, inside one of the malls or in your own neighbourhood. Message ahead on WhatsApp to ask for a slot, the price and how long it takes, especially for after-work or Saturday visits.
Where to look for a hair salon in Mariano Roque Alonso
- Along Ruta PY03 (the old Transchaco): the city's main road (Wikipedia (opens in a new tab)). Handy if you drive it every day towards Asunción or Limpio.
- In the malls: the city has Shopping Mariano, La Rural Shopping and Paseo Alameda (Wikipedia (opens in a new tab)). A salon inside a mall gives you parking, air conditioning and something to do if you came with company.
- In your neighbourhood: if you live in Surubi'i, San Blas, Villa Margarita, Remanso or Monseñor Bogarín, a nearby salon or barber saves you crossing the highway for a quick cut.
Searching for a walk-in salon or one open now? Don't rely on map listings alone: send a message and ask whether they can take you within the next hour.
How to fit your appointment around Transchaco traffic
PY03 clogs at rush hour. In May 2026, passengers were waiting up to half an hour for buses on the Transchaco just after 7:00 (ABC Color (opens in a new tab)), and rain or a crash can jam traffic towards Asunción all morning (Última Hora (opens in a new tab)).
- Pick a salon on the side of the highway you drive home on.
- Book colour, highlights or straightening (which take hours) on a day off, not after work.
- In July, during the Asociación Rural del Paraguay Expo (11 to 26 July in 2026, per ABC Color (opens in a new tab)), the area fills up, so book further ahead.
Cut, colour or straightening: what to ask
- Cut or beard: ask whether they take walk-ins or only appointments, and the price with and without a wash.
- Colour and highlights: ask for the final price for your hair length and whether treatment is included. If it's your first time with a dye, ask for a patch test first.
- Straightening: ask which product they use and look at the packaging. In Brazil, Anvisa bans formaldehyde as a straightening agent and allows it only as a preservative up to 0.2% (Itatiaia, 2025 (opens in a new tab)). If your eyes burn or breathing gets hard during the service, ask them to stop.
- Time: confirm how long the whole job takes so you're not stuck halfway through.
Registered products, and treatments that don't belong in a salon
DINAVISA, Paraguay's health products regulator, advises against buying unregistered products because they can cause allergic reactions, and says the registration number must appear on the packaging (Última Hora (opens in a new tab)).
Fillers, biostimulators and other injectables are not salon work. The Paraguayan Society of Aesthetic Medicine warns they must be done in a clinic licensed by the Health Ministry and the Health Superintendency, by a trained doctor, not in hair salons or at home (La Nación (opens in a new tab)). In October 2026, DINAVISA warned about two unregistered cosmetic injectables (Sculptra and Power col-tra) that entered the country through unauthorised channels, and asks people to demand proof of registration and origin before any treatment (ABC Color (opens in a new tab)).
Paying and getting an invoice
QR is now the most used method: in April 2026 it accounted for 68.1% of electronic payments processed by Bancard (ABC Color (opens in a new tab)). Still, ask what they accept (QR, card, bank transfer) and carry some cash in guaraníes. Sedeco, the consumer protection office, reminds businesses that every sale of goods or services must come with an invoice (ABC Color (opens in a new tab)), so ask for a factura if you need one.
Quick check before you book
- Recent photos of their work on Instagram or Facebook, ideally the cut or colour you want.
- Today's hours: Saturdays and public holidays differ.
- Parking or a bus stop nearby.
- A fast WhatsApp reply, which usually says a lot about how they manage bookings.
