The Biology of Beauty

Scientist, Author & Beauty Innovation Entrepreneur

Why skin, hair and ageing aren’t one-size-fits-all.

Dr Sola Idowu is a scientist, author and beauty innovation entrepreneur exploring why skin, hair and ageing don’t follow one-size-fits-all biology, and how AI and computational biology could help build a more inclusive generation of beauty products.

Science behind the beauty conversation

Dr Sola Idowu works at the intersection of science, technology and beauty innovation.

What happens when we stop treating human skin, hair and ageing as if they all follow the same biological rules?

He is the author of Melanin: The Science of Skin, Colour, and the Biology We Share, Rooted: The Hidden Science of Textured Hair and the Scalp, and Ageing: The New Science of How We Age, Across Every Phenotype. Together, the books challenge conventional classification systems and explore the biological differences that shape skin, hair and ageing.

He is also Founder and CEO of HexisLab, an AI and computational-biology company working across cosmetics, personal care, wellness and pharmaceutical research.

WHY INVITE SOLA?

Why invite Sola?

Beauty is often discussed through products, ingredients and trends. Sola brings a different perspective: the biology underneath them.

He can translate complex scientific research into conversations that are relevant to consumers, clinicians, beauty professionals, founders and the wider public.

His work sits at the intersection of:

  • Skin biology and melanin
  • Textured hair and scalp science
  • Ageing across different phenotypes
  • Inclusive dermatology and the research gap
  • Cosmetic formulation and evidence
  • AI and computational biology
  • Personalised beauty
  • Science-led beauty entrepreneurship

Sola is particularly interested in the gap between what the research tells us, what the beauty industry sells us, and what consumers actually need.

He brings both scientific depth and commercial experience: alongside his research and writing, he leads HexisLab, where AI, computational biology, laboratory research and formulation are brought together to develop new ingredients, products and evidence for beauty and personal-care applications.

He doesn’t just explain the science. He works on what comes next.

PODCAST CONVERSATIONS

Nine conversations Sola can bring to your audience

01

The Biology of Beauty: Why One-Size-Fits-All Doesn’t Work

For decades, beauty has divided people into simple categories: skin types, hair types and age groups. But biology is considerably more complicated. Sola explores why pigmentation, barrier function, inflammation, hair structure and ageing don’t necessarily travel together, and what this means for the future of personalised beauty.

Best for: General beauty, science, consumer and wellness podcasts.

02

Beyond Fitzpatrick: What the Biology of Melanin Really Tells Us

The Fitzpatrick scale has shaped dermatology, skincare and public health for decades, but what was it actually designed to measure? Sola explores what the scale can tell us, what it cannot, and why understanding the biology behind melanin matters for pigmentation, UV exposure, inflammation, scarring and personalised skincare. This connects directly to the argument in Melanin.

Best for: Dermatology, medical, science and skin-health podcasts.

03

The Scalp Is Skin: The Hidden Biology of Textured Hair

Curl pattern is visible. Hair biology is not. Sola explores follicle structure, scalp biology, inflammation, textured hair, hair loss and why conventional hair-typing systems can be a poor substitute for understanding what is actually happening biologically. His work on textured hair also extends into published research examining genomic variation and its implications for haircare.

Best for: Hair, beauty, Black culture, dermatology and founder podcasts.

04

Why We Don’t All Age the Same Way

Wrinkles aren’t the only measure of ageing. Sola explores why different skin phenotypes can experience different visible manifestations of ageing, and why pigmentary, textural, scalp and follicular changes deserve much more attention. This is the central argument explored in Ageing.

Best for: Beauty, wellness, women’s health, healthy ageing and lifestyle podcasts.

05

The Beauty Industry Has a Biology Problem

Why are so many beauty products still developed around broad demographic categories rather than biological differences? Sola discusses what happens when we combine biology, AI, laboratory science and formulation to approach beauty development differently. HexisLab’s current work explicitly combines AI-guided discovery, laboratory validation and formulation development.

Best for: Business, beauty-industry, technology, AI and entrepreneurship podcasts.

06

From Research to Beauty Product: What Does “Science-Backed” Actually Mean?

“Science-backed” has become one of beauty’s favourite phrases. But what evidence should actually sit behind a skincare or haircare claim? Sola can take listeners through the journey from biological hypothesis, to ingredient discovery, to testing, to formulation, to evidence, to consumer claim.

Best for: Cosmetic science, beauty-business, founder and consumer podcasts.

07

Can AI Finally Make Beauty Genuinely Inclusive?

Beauty products have often been developed around limited datasets, narrow consumer groups and simplified categories of skin and hair. Sola explores whether AI and computational biology can help move the industry from designing for an “average consumer” towards products informed by real biological diversity.

Best for: AI, technology, beauty, entrepreneurship, diversity and future-of-industry podcasts.

08

Can Beauty AI Be Biased?

If the data doesn’t represent everyone, can the algorithm really create inclusive products? Sola can discuss biased datasets, underrepresented skin and hair biology, the gap between demographic labels and true biological diversity, what “inclusive data” actually means in practice, and why laboratory validation remains essential however convincing a model looks on paper.

Best for: AI ethics, technology, beauty-industry and general AI podcasts.

09

From Months to Weeks: Can AI Compress the Beauty R&D Cycle?

Developing a new cosmetic ingredient or formulation can involve enormous amounts of research, experimentation and testing. Sola discusses how AI and computational biology can help compress that R&D cycle, from biological hypothesis to ingredient discovery, formulation and validation, while keeping laboratory science and evidence at the centre, and what AI can, and cannot, replace in scientific research.

Best for: AI, technology, business, beauty-industry and founder podcasts.

AI, BIOLOGY & THE FUTURE OF BEAUTY

AI, Biology & the Future of Beauty

Can we use artificial intelligence to build a beauty industry that understands biological diversity, rather than averaging it away?

At HexisLab, Sola is exploring how AI and computational biology can accelerate scientific discovery: from identifying promising biological targets and ingredients, to supporting formulation development and evidence generation.

The goal isn’t to replace scientists or laboratories. It’s to help scientists ask better questions, explore more possibilities and reach evidence faster.

MELANIN

The Science of Skin, Colour, and the Biology We Share

What happens when a six-point classification system becomes the default language for understanding the world’s skin? Melanin examines the limits of the Fitzpatrick scale and explores the biological variables that sit underneath visible pigmentation.

Rooted book cover — The Hidden Science of Textured Hair and the Scalp, by Dr Olusola Idowu

ROOTED

The Hidden Science of Textured Hair and the Scalp

Curl pattern is not the same thing as hair biology. Rooted explores textured hair through follicle science, scalp biology, inflammation and the biological factors that shape hair health.

Ageing book cover — The New Science of How We Age, Across Every Phenotype, by Dr Olusola Idowu

AGEING

The New Science of How We Age, Across Every Phenotype

Not every skin ages primarily through wrinkles. Ageing explores the biological mechanisms behind skin ageing and why the visible signs of ageing can differ substantially across phenotypes.
