Intricate Hair Loss Analysis using AI
The umbrella of AI includes computer vision and deep learning techniques that effectively analyze high-resolution videos and images of the patient or subject’s scalp and hair follicles, which can even be used for clinical trial data analysis. Since these AI models utilize vast large training, testing and validation datasets of hair and scalp images, they can quickly identify similar patterns and signs of hair loss in the images obtained in real time, classify severity of the condition, provide diagnostic results and recommend personalized treatment.
Procedure
Given below is the step-by-step process followed by AI-based hair analysis:
Hair & Scalp Image Acquisition
The initial step involves obtaining several high-resolution images of hair follicles, the entire scalp and areas if visible thinning or hair loss for diagnosis. These images are captured using dermatoscopes, smartphones, or other specialized imaging devices.
Preprocessing & Data Augmentation
The acquired images are preprocessed to enhance their quality and the data extracted, and they undergo resizing, denoising, and normalizing for further hair loss diagnosis and analysis. Here, data augmentation involves rotating, flipping and cropping images to increase the dataset variability, which leads to the model’s robustness.
Feature Extraction & Analysis
Convolutional Neural Networks (CNNs) and other deep learning models are used to extract features such as hair density, follicle size, presence of scarring or inflammation etc. from the images obtained. The models then detect patterns associated with hair loss from these extracted features for further diagnosis.
Diagnosis & Classification
Hair loss severity is classified into mild thinning to advanced baldness as per the features extracted from the images. The observed patterns are used to provide insights into types of hair loss such as androgenic alopecia, telogen effluvium etc.
Personalized Recommendations
These models also suggest personalized treatment recommendations as per the diagnosed condition, for example, options such as medications (minoxidil, finasteride), hair transplant procedure, lifestyle changes, care routine etc.
Techniques
Several AI models have been employed in hair analysis for hair loss, focusing on scalp and hair analysis. Some of these techniques are given below:
Convolutional Neural Networks (CNNs)
This is the most common type of deep learning technique that is used for hair analysis and loss diagnosis through feature extraction, pattern recognition and machine learning. These analyze high-resolution images of the scalp and follicles and detect minute details in the images including hair density, follicle health symptoms of thinning, even at early stages which may not be visible to naked eye.
Generative Adversarial Network (GANs)
These involve two networks – generator and discriminator, where the former generates synthetic images of follicles which are compared with real images by the discriminator to improve the model’s ability of detecting subtle changes in hair density. In cases of lack of high-quality annotated data usually developed by data annotation services GANs can be used to train models.
Transfer Learning
This technique of hair loss diagnosis involves pre-training models on large datasets and fine-tuning them for specific tasks including hair loss diagnosis. This helps overcome the challenge of limited annotated data in specialized domains such as dermatology in the case of AI skin analysis . Large-scale image datasets, for example, ImageNet, are leveraged by these models to adapt quickly to specialized tasks for accurate results.
Image Segmentation
In this process, the image is divided into multiple segments or regions for isolating specific features for region-wise analysis, such as scalp affected by hair thinning versus unaffected areas. Users obtain a more targeted analysis of scalp condition, hair density and follicle health for precise diagnosis.
Optical Coherence Tomography (OCT)
It is a non-invasive imaging technique that can be combined with AI models to provide high-resolution cross-sectional images of scalp and hair follicles. This results in enhanced scalp and hair analysis, early signs of damage in follicle health or miniaturization such as in case of androgenic alopecia.
Use Cases of Hair Loss Diagnosis
By integrating computer vision and deep learning techniques for hair care and diagnostics, a wide range of use cases can be devised for various domains including healthcare, dermatology clinics for hair or customized skincare solutions etc., some of which are given below:
1. Telemedicine: AI-powered hair analysis is being used widely nowadays for telemedicine and remote consultations.
