Well we don't know how witnesses have described him, but the only evidence I've seen that he had short hair at the time was provided by the Daily Mail.

I can't find any details of this trip elsewhere online.
I really do not think you tried very hard then. I had no difficulty finding provenance of the Mail article. Amaral lied. He was caught out in his lies ~ which when you think about it, was a pretty whopping great lie designed to falsify the physical appearance of the prime suspect in a missing child case.
There sure are questions arising for him regarding that and I think it probable that one day he may be required to provide answers to them.
Footage surfaced!
Shortly before Maddie's disappearance: Here Christian B. drives tourists through Portugal
August 01, 2020 - 12:55 PM
He drove the car in which he is said to have kidnapped Maddie
He allegedly kidnapped Madeleine McCann in 2007 at a resort in Praia da Luz, Portugal, and murdered her. Now footage of Christian B. has surfaced showing the Maddie suspect on a road trip through the town – a few weeks before the disappearance of the then 3-year-old. Of all things, with the van in which he is said to have kidnapped the girl. More about this in the video.
Three Germans on the road with Christian B.
He laughs, he jokes. Christian B. has three German travellers in tow, whom he takes with him from Spain to Portugal, reports the Daily Mail. On the picture: B. sits in the car of the model T3 Westfalia over a map and has fun with his guests. Only a few weeks later, the convicted sex offender is said to have kidnapped Madeleine McCann with exactly this car.
One of the tourists – a man named Tomas – told the Daily Mail: "It makes me sick to think that the little girl could have been taken away in the same van a month later."
Little Maddie is said to have been kidnapped in the van
The video was shot on March 30, 2007, just five weeks before Madeleine disappeared from her Portuguese holiday home in Praia da Luz. In retrospect, his traveller Tomas was surprised that B. had been filmed, he said. "He didn't mind that we filmed him and took his pictures. He enjoyed posing – he must have known that we could never have guessed what a terrible man he really was," says the German. It is frightening to know that he raped a woman and was a convicted child molester.https://www.rtl.de/cms/fall-maddie-aufnahmen-aufgetaucht-hier-faehrt-christian-b-im-van-durch-portugal-4587932.htmlThis road trip happened. Video footage from it revealed Brueckner's true appearance just before Madeleine's disappearance which was directly opposite to the description broadcast by Amaral just a few weeks before.
Amaral didn't know about the existence of this video which proved him to be a liar. Not only a liar but someone anxious to put about false information in an attempt to destroy an active police investigation.
You may be content to attempt to obfuscate the misdeeds of a person like that which is entirely your prerogative but misleading the forum is a bit of a No! No!
