    it's working!!!

    I have been using Vegamour GRO serum for more than a year, although not daily because I tend to forget. The only other change I have made during that time is that I also started using a collagen powder in my coffee most mornings. I can definitely see a huge difference from a year ago - especially the corners of my forehead have filled in with new hair and my hairline, overall looks a lot better. It used to be a huge hang up for me but now I barely think of my hair as an issue. I am 52.

    It works

    I have had a positive experience with Vega more. Except surprisingly it took at least a year before I saw noticeable results. I had read you could tell after a month or two months for me. It was a year until I could see results. The areas of hair loss or thinning hair did not grow long hair, but almost like fur. It’s short, but it covers my scalp. You can see the pictures that I’ve included, but I continue to use it and I have started using it on my husband and I think his hair is also thinking. I would love to pay to be a gray herd endorse or endorsement but for now I’ll keep paying and keep using this stuff. I am pretty diligent about using it every day. I don’t think I miss too many.

    Perfecto

    ¡Chicas y chicos, tengo que contarles algo que me tiene súper emocionada! Últimamente he estado buscando una solución real para sentir mi cabello más fuerte y con más volumen, y ¡creo que finalmente la encontré!

    Les hablo del Suero Capilar de Prestigio N.º 1 (sí, así con asterisco de importante 😉). Lo que me convenció fue su fórmula que combina células madre de cúrcuma, cafeína y extractos naturales que suenan increíbles para el cuero cabelludo. Además, ¡prometen resultados en solo 3 meses!

    Después de investigar un poco (y leer algunos testimonios), me animé a probarlo. La aplicación es súper fácil, solo unas gotitas después de la ducha y listo. No es grasoso ni nada, lo cual es un gran plus.

    Si ustedes también están buscando un empujón para tener un cabello más denso y fuerte, ¡les recomiendo echarle un vistazo a este suero! Yo les iré contando cómo me va, pero las primeras impresiones son muy buenas. ¡A darle una oportunidad a ese pelazo que siempre hemos querido! ✨
