Melania Trump turned 50-years-old in April. But, despite her advancing age, the First Lady has maintained her youthful glow and appearance.

Aside from her fashion pieces and beauty routines, an expert asserted that she has another "instant anti-aging" trick that seemingly helps her look much younger. As stated, this has something to do with her hair.

The First Lady has a "signature blow-dry" hair, according to the Daily Express. She, reportedly, appears to look the same in each of her engagements and appearances.

While the public may not notice it, the publication said that hair experts know about the little changes she has done over the years. Amid trying to stay "consistent" with her hair color and hairstyle, they said that the President's wife was a bit "playful" with her hair, especially before her time inside the White House.

Speaking to the same publication, HARI's Creative Colourist Francesca Dixon said that Melania Trump has "very dark" roots, which drag down into much lighter mid-lengths. But, over time, she, reportedly, changed it "little by little."

Dixon claimed that, based on the First Lady's photos, her hair has become way lighter than before. She, then, noted that having small color changes helps the hair maintain its "health" and "wellbeing." 

The expert continued and explained that Melania has "framed" her face around the hairline using lighter tones. She claimed that this is likely Trump's "secret" to her youthful glow and appearance, adding that this has had an "anti-aging" effect on her.

Melania Trump, also, reportedly, styles her hair that makes it appears much "thicker." Dixon asserted that this is another trick that can help soften facial features, causing an instant anti-aging effect.

She explained that hair naturally thins as one age. But, with this kind of style, alongside the gradual change of color, it can provide a more youthful appearance.

Aside from her hair, Melania Trump has other "dos and don'ts" that help her with her health and wellness. The Cut reported that these things do not only make her look young but, they, also, help her with her figure.

Among all, the First Lady, reportedly, values her sleep so much. Even before her marriage to Donald Trump, sources said that she "rarely" partied.

The publication, then, added that Melania always eats seven fruits per day. Alongside the nutritious snacks, she stays consistent with her exercise routines.

As for her skin, sources revealed that she likes to moisturize all the time. However, she, allegedly, stated that she does not let others see her without makeup.
