"Severus, I just have to ask. What have you been doing with yourself? You look 15 years younger!"

Severus gave a slightly pained smile. "I've been working with Mr. and Mrs. Granger on bringing proper tooth care to the Magical world. They saw that there seemed to be a lack of it and decided to invest time and resources in to opening up a shop. They are testing different potions and magical procedures right now, so that they can open their new shop in the New Year."

Both Malfoys looked at their guests in astonishment. "Magical procedures?" Lucius asked. "I thought they were Muggles."

Severus shrugged. "They have hired a few Mediwitches and others to help. They are trying to ensure that the Witches and Wizards who take their services get the benefit of magic when possible rather than relying on Muggle means. They believe this will make it much more acceptable for purebloods."

Lucius chewed his last bite even as he contemplated the last comment. When he finally swallowed he said, "Well. It seems Ms. Granger's lauded intelligence seems to come to her honestly. Who knew that Muggles could have such discernment?"

Narcissa almost dismissed that path of conversation and got to what she really wanted to know. "That's all well and good, but how does that explain your other improvements? You know we love you, but even you would have to admit that your hair was never your best feature. Now, it practically shines! How did that happen?"

Serverus gave a reply which surprised them almost as much as it had surprised him when he learned of it. "Actually, that was just a byproduct. During the first phase of testing, they have a licensed mediwitch perform a procedure to find out if the patient has any allergies."

"Allergies?" Narcissa asked. "What are those?" Purebloods were somewhat unfamiliar with Muggle knowledge.

Severus, having just finished his main course, set down his fork and sat back. "Apparently, about a century ago, a Muggle healer found that different people reacted poorly to substances which were commonly used in medicines. They found that something that provided aid to one person could act as a deadly poison to another. As a result, they came up with a system to test to see what substances people react poorly to."

Narcissa was highly interested, even as her husband was. "How does it work?"

"Well, they use the substances in extremely small amounts and see what reactions people have. They then record what the patient reacts poorly to and ensure that these substances are not used to treat the patient." Severus gave a look which had much zeal in it. "I'm going to continue testing and write an article for it in a few publications." He gathered himself. "Anyway, they found I had an allergy toward one of the ingredients used in a potion that brewers often take to cleanse their system of any accidentally imbibed fumes. I found that instead of keeping myself healthy, I was – in effect – poisoning myself regularly. One small change and …," he pointed to the hair atop his head.
